Consistent with the present disclosure, a compact laser with extended tunability (CLET) is provided that includes multiple segments or sections, at least one of which is curved, bent or non-collinear with other segments, so that the CLET has a compact form factor either as a singular laser or when integrated with other devices. The term CLET, as used herein, refers to any of the laser configurations disclosed herein having mirrors and a bent, angled or curved part, portion or section between such mirrors. If bent, the bent portion is preferably oriented at an angle of at least 30 degrees relative to other portions of the CLET. Alternatively, the curve or bend portion may be distributed over different sections of the CLET over a series of arcs, for example. The waveguide extending between the mirrors is continuous, such that light propagating along the waveguide is not divided or split. The waveguide also constitutes a continuous waveguide path.

Photonic integrated circuit including compact lasers with extended tunability

Consistent with the present disclosure, a photonic integrated circuit (PIC) is provided that has 2 N channels (N being an integer). The PIC is optically coupled to N optical fibers, such that each of N polarization multiplexed optical signals are transmitted over a respective one of the N optical fibers. In another example, each of the N optical fibers supply a respective one of N polarization multiplexed optical signals to the PIC for coherent detection and processing. A multiplexer and demultiplexer may be omitted from the PIC, such that the optical signals are not combined on the PIC. As a result, the transmitted and received optical signals incur less loss and amplified spontaneous emission (ASE) noise. In addition, optical taps may be more readily employed on the PIC to measure outputs of the lasers, such as widely tunable lasers (WTLs), without crossing waveguides.

Optical modules having an improved optical signal to noise ratio

Methods, systems, and apparatus, including a laser including a layer having first and second regions, the first region including a void; a mirror section provided on the layer, the mirror section including a waveguide core, at least part of the waveguide core is provided over at least a portion of the void; a first grating provided on the waveguide core; a first cladding layer provided between the layer and the waveguide core and supported by the second region of the layer; a second cladding layer provided on the waveguide core; and a heat source configured to change a temperature of at least one of the waveguide core and the grating, where an optical mode propagating in the waveguide core of the mirror section does not incur substantial loss due to interaction with portions of the mirror section above and below the waveguide core.

Tunable waveguide devices

Methods, systems, and apparatus, including a photonic integrated circuit package, including a photonic integrated circuit chip, including an active optical element; an electrode configured to receive an electrical signal; a ground electrode; and a bond contact electrically coupled to the electrode; and an ASIC chip including circuitry configured to provide the electrical signal; and a bond contact that is electrically coupled to the circuitry; an bridge chip bonded to at least a portion of the photonic integrated circuit chip and at least a portion of the ASIC chip.

Photonic integrated circuit package

A device may include a substrate. The device may include a carrier mounted to the substrate. The device may include a transmitter photonic integrated circuit (PIC) mounted on the carrier. The transmitter PIC may include a plurality of lasers that generate an optical signal when a voltage or current is applied to one of the plurality of lasers. The device may include a first microelectromechanical structure (MEMS) mounted to the substrate. The first MEMS may include a first set of lenses. The device may include a planar lightwave circuit (PLC) mounted to the substrate. The PLC may be optically coupled to the plurality of lasers by the first set of lenses of the first MEMS. The device may include a second MEMS, mounted to the substrate, that may include a second set of lenses, which may be configured to optically couple the PLC to an optical fiber.

Hybrid optical transmitter and/or receiver structure

Methods, systems, and apparatus, including a photonic integrated circuit package, including a photonic integrated circuit chip, including multiple electrodes configured to receive the electrical signal, where at least one characteristics of a segment of the traveling wave active optical element is changed based on the electrical signal received by a corresponding electrode of the multiple electrodes; a ground electrode; and multiple bond contacts; and an interposer bonded to at least a portion of the photonic integrated circuit chip, the interposer including a conductive trace formed on a surface of the interposer, the conductive trace electrically coupled to a source of the electrical signal; a ground trace; and multiple conductive vias electrically coupled to the conductive trace, where each conductive via of the multiple conductive vias is bonded with a respective bond contact of the multiple bond contacts of the photonic integrated circuit chip.

Methods, systems, and apparatus, including a photonic integrated circuit package, including a photonic integrated circuit chip, including a lumped active optical element; an electrode configured to receive an electrical signal, where at least one characteristics of the lumped active optical element is changed based on the electrical signal received by the electrode; a ground electrode; and a bond contact electrically coupled to the electrode; and an interposer bonded to at least a portion of the photonic integrated circuit chip, the interposer including a conductive trace formed on a surface of the interposer, the conductive trace electrically coupled to a source of the electrical signal; a ground trace; and a conductive via bonded with the bond contact of the photonic integrated circuit chip, the conductive via electrically coupled to the conductive trace to provide the electrical signal to the electrode of the photonic integrated circuit chip.

A semiconductor monolithic transmitter photonic integrated circuit (TxPIC) comprises two different situations, either at least one signal channel in the PIC having a modulated source with the channel also extended to include at least one additional element or a plurality of modulated sources comprising N signal channels in the PIC of different transmission wavelengths, where N is equal to or greater than two (2), which may also approximate emission wavelengths along a standardized wavelength grid. In these two different situations, a common active region for such modulated sources and additional channel elements is identified as an extended identical active layer (EIAL), as it extends from a single modulated source to such additional channel elements in the same channel and/or extends to additional modulated sources in separate channels where the number of such channels is N equal to two or greater. The emission wavelength of laser sources in the modulated sources have different positively detuned offsets of the laser emission wavelength relative to the laser active region wavelength, i.e., (&#x3bb;&#x2212;&#x3bb;&#x3e;0), and their emission wavelengths form a wavelength grid which may substantially conform to a standardized wavelength grid, such as the ITU grid. These laser sources in the modulated sources with an EIAL are preferentially detuned in the range, for example, of about 20 nm to about 70 nm, preferentially from about 25 nm to about 50 nm, from the active region wavelength of the modulated sources.

Monolithic photonic integrated circuit (PIC) with a plurality of integrated arrays of laser sources and modulators employing an extended identical active layer (EIAL)

A laser source or a plurality of laser sources in a photonic integrated circuit (PIC) are provided with an electrical contact that is either segmented or is connected to a series of vernier resistor segments for supply of current to operate the laser source. In either case, at least one segment of the laser contact or at least one vernier resistor segment can be trimmed in order to vary the amount of current supplied to the laser source resulting in a change to its current density and, thus, a change in its operational wavelength while maintaining the current supplied to the laser source constant.
