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

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 an optical receiver including an optical source, including a substrate; a laser provided on the substrate, the laser having first and second sides and outputting first light from the first side and second light from the second side, the first light output from the first side of the laser has a first power and the second light output from the second side has a second power; and a first modulator that receives the first light and a second modulator that receives the second light, such that the power of the first light at an input of the first modulator is substantially equal to the power of the second light at an input of the second modulator.

Photonic integrated circuit

Methods, systems, and apparatus, including an optical receiver including a laser including a gain section; and a first tunable reflector configured to output a reference signal; a first coupler formed over the substrate; a shutter variable optical attenuator formed over the substrate, the shutter variable optical attenuator including an input port configured to receive the first portion of the reference signal from the laser; and an output port configured to provide or to block, based on a control signal, the first portion of the reference signal from the laser; and a second coupler including a first port configured to receive the first portion of the reference signal from the shutter variable optical attenuator; and a second port configured to (i) provide the first portion of the reference signal from the shutter variable optical attenuator to an optical analyzer or (ii) receive a data signal from a transmitter.

Consistent with the present disclosure, both arms of an MZ interferometer are 'double-folded' and are bent in at least two locations to define first and second acute inner angles. Accordingly, the arms of the MZ interferometer may have substantially the same length, and, further, the MZ interferometer has a more compact geometry. In one example, the arms parallel each other and have a serpentine shape, and, in a further embodiment, the arms parallel one another and have a Z-shape. Accordingly, since the temperature of a PIC upon which the MZ interferometer is provided does not vary significantly over such short distances, the temperatures of both arms is substantially the same.

A Raman pump may include a dual output laser configured to output two optical signals; a delay interferometer configured to delay a first of the two optical signals to decorrelate the two optical signals from each other; and a combiner configured to combine the delayed first of the two optical signals and a second of the two optical signals to provide a Raman amplification signal.

A device may include a number of optical waveguides, each of which being spaced from one another. The optical waveguides may each include at least one curved section and widths of the curved sections of the optical waveguides may be selected to reduce polarization conversion of light traversing the birefringent optical waveguides.

Suppression of resonant polarization conversion in photonic integrated circuits

The present invention provides for a semiconductor laser having a narrow linewidth and low power consumption for optical communication applications. According to various embodiments of the invention, a semiconductor laser is provided which includes a grating layer comprising a plurality of segmented gratings, each including a non-grating portion and a grating portion. The segmented gratings are configured to enhance a fundamental mode of the semiconductor laser while sufficiently suppressing modes other than the fundamental mode, providing a narrow linewidth for example. The segmented gratings are also configured to provide an effective length longer than an actual length of the semiconductor laser, leading to smaller device areas and corresponding lower power consumption. A photonic integrated circuit is also provided which includes a plurality of semiconductor lasers, consistent with the present invention, as well as additional optical elements, all provided on a single substrate.
