Abstract: Some embodiments of the present disclosure are directed to a detachable connector for a co-packaged optics (CPO) device. The detachable connector may include a kinematic mount, where the kinematic mount includes a first kinematic interface configured to engage a corresponding kinematic interface of the CPO device. In some embodiments, the kinematic mount is configured for repeated detachment and attachment with substantially identical alignment between the detachable connector and the CPO device within a predetermined sub-micron tolerance. Furthermore, in an attached state, the kinematic mount may be configured to provide an optical transmission path between the CPO device and the detachable connector, where a transmission loss along the optical transmission path remains within a predetermined threshold tolerance.

Abstract: Systems, methods, and computer program products are described for a redundant external laser source in optical systems (e.g., CPO systems). An example system may include a plurality of ELS units, a RELS unit, an optical switch, and a plurality of optical couplers, and a control unit. The control circuit may be configured to detect an operational failure of a first ELS unit. In response to detecting such a failure, the control circuit may configure the RELS unit to replace the first ELS unit and, using the optical switch, substitute the first ELS unit with the RELS unit. Such a configuration ensures continuous system performance by dynamically replacing failing ELS units with redundant ELS units, thereby reducing downtime and enhancing the reliability of the optical communication system.

Abstract: An optical circuit includes solid state photonics. The optical circuit includes a phased array of solid state waveguides that perform beamsteering on an optical signal. The optical circuit includes a modulator to modulate a bit sequence onto the carrier frequency of the optical signal, and the beamsteered signal includes the modulated bit sequence. The optical circuit includes a photodetector to detect a reflection of the beamsteered optical signal. The optical circuit autocorrelates the reflection signal with the bit sequence to generate a processed signal.

Abstract: An optical pulse generator, consisting of a semiconductor device and an optical output assembly. The semiconductor device includes an optically-active region having a gain section and a saturable absorber (SA) section, which are adapted to generate coherent optical pulses. The device also includes an output facet for coupling therethrough of the optical pulses generated in the optically-active region, and an SA electrode for application of a radio-frequency (RF) modulation of a desired frequency to the SA section. The optical output assembly is optically coupled to the output facet of the semiconductor device so as to partially reflect the coherent optical pulses within a predetermined wavelength range.
