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).

Optical comb source for content-addressable memory encoders

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.
