Abstract: One embodiment provides an optical encoder. The optical encoder includes an optical comb source to generate a multi-wavelength optical signal; a number of optical filters sequentially coupled to the optical comb source, with a respective optical filter being tunable to pass or block a particular wavelength of the multi-wavelength optical signal based on a corresponding bit value of a multi-bit search word; and a common output for the optical filters to output the filtered multi-wavelength optical signal, which encodes the multi-bit search word and can be used as an optical search signal for searching an optical content-addressable memory (CAM).

Abstract: Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including a bidirectional optical link such as an optical fiber. The optical system includes a resonator tuned to filter a resonant wavelength of light emitted by an optical source. The optical source may be configured to emit light having multiple wavelengths, and the resonator may be configured to receive light emitted by the optical source. The optical system may further include a photodetector to receive the resonant wavelength and measure a power of the resonant wavelength. The optical system may further include a controller coupled to the optical source. The controller may receive the measured first power of the resonant wavelength and change the state of the optical source when the measured power of the resonant wavelength is outside a per-wavelength threshold range.

Abstract: Narrow-optical linewidth laser generation devices and methods for generating a narrow-optical linewidth laser beam are provided. One narrow-optical linewidth laser generation devie includes a single-wavelength mirror or multiwavelength mirror (for comb lasers) formed from one or more optical ring resonators coupled with an optical splitter. The optical splitter may in turn be coupled with a quantum dot optical amplifier (QDOA), itself coupled with a phase-tuner. The phase tuner may be further coupled with a broadband mirror. The narrow-optical linewidth laser beam is generated by using a long laser cavity and additionally by using an integrated optical feedback.

Abstract: A coupler/splitter including two neighboring coplanar waveguide portions extending in a same direction, the first portion having a constant cross-section, the second portion having a variable cross-section so that the effective index of the second waveguide portion varies, in the upstream-to-downstream direction, from a first lower value to a second value higher than the effective index of the first portion, in adiabatic coupling conditions.

Abstract: The laser device includes an amplifier including a III-V heterostructure arranged to generate photons, and a waveguide which forms a loop and is optically coupled to the amplifier. The amplifier is arranged facing the waveguide only in the region of a first section of the waveguide.
