A method or apparatus for narrowing the linewidth of a single mode laser is provided. The linewidth of a single mode laser is narrowed by injecting an optical feedback simultaneously into the first laser cavity mirror and the second laser cavity mirror of the single mode laser.

Method for narrowing the linewidth of a single mode laser by injecting optical feedback into the laser cavity through both laser cavity mirrors

Two semiconductor chips are optically aligned to form a hybrid semiconductor device. Both chips have optical waveguides and alignment surface positioned at precisely-defined complementary vertical offsets from optical axes of the corresponding waveguides, so that the waveguides are vertically aligned when one of the chips is placed atop the other with their alignment surface abutting each other. The position of the at least one of the alignment surface in a layer stack of its chip is precisely defined by epitaxy. The chips are bonded at offset bonding pads with the alignment surfaces abutting in the absence of bonding material therebetween.

Optically aligned hybrid semiconductor device and method

A fiber alignment or 'fiberposer' device enables the passive alignment of one or more optical fibers to a photonic integrated circuit (PIC) device using mating hard-stop features etched into the two devices. Accordingly, fiber grooves can be provide separate from the electrical and optical elements, and attached to the PIC with sub-micron accuracy. Fiberposers may also include a hermetic seal for a laser or other device on the PIC. All of these features significantly reduce the typical cost of an actively aligned optical device sealed in an hermetic package.

Optical fiber alignment device

An apparatus for controlling, monitoring, and communicating with an optical device, photonic integrated circuit or subassembly is provided. The apparatus includes an optical device or subassembly; and afield programmable device including programmable hardware gates coupled to the optical device or subassembly. The field programmable device may be configured to implement a plurality of functions at a gate level for controlling, monitoring, and/or communicating with the optical device or subassembly, each of the plurality of functions being configured to execute as a concurrent process, without use of a microprocessor or a microcontroller. Further, a programmable optical device, such as a programmable optical transmitter, optical subassembly, or transceiver based on a tunable laser having field programmable device centric control systems with software-enabled features offer extensive real-time control and monitoring functionality based on for example actual traffic flows.

Method and apparatus for controlling, monitoring, and communicating with tunable optical devices and subassemblies

A method and apparatus for calibrating and controlling tunable lasers are disclosed. Multiple methodologies disclosed herein may be used, alone or in combination, which significantly speed up a calibration time and thus provide a significant advantage over existing technology in calibrating the tunable lasers. Certain methodologies benefit from a unique design of the tunable lasers that couple two or more optical facets to an output. The tunable lasers may be equipped with two or more sampled grating distributed Bragg reflector (SGDBR) mirrors and may include Semiconductor Optical Amplifiers (SOAs) after the SGDBR mirrors.
