Abstract: An opto-mechanical assembly includes a first thermal control element disposed on a region of a first section of an enclosure; a second thermal control element disposed on a region of a second section of the enclosure; and an optical element that includes a first portion and a second portion. The first thermal control element is configured to heat the first portion of the optical element and to cause the first portion of the optical element to be associated with a first temperature, and the second thermal control element is configured to heat the second portion of the optical element and to cause the second portion of the optical element to be associated with a second temperature. This causes a difference between the first temperature and the second temperature to satisfy a temperature difference threshold. Accordingly, this also causes a temperature gradient along an axis of the optical element to satisfy a temperature gradient threshold.

Abstract: A method may include receiving, by a switching engine, an optical signal that includes a channel. The method may include applying, by the switching engine, a first beam steering grating to direct a first portion of the channel to a first output port. The method may include applying, by the switching engine, one or more second beam steering gratings to direct at least one of a second portion of the channel to a second output port, or a third portion of the channel to a photodetector. The third portion may be approximately less, in power, than 10 percent of the channel.

Abstract: A pluggable optical module may include a substrate. The pluggable optical module may include a compressible sliding thermal interface disposed on the substrate to contact a riding heatsink. The compressible sliding thermal interface material may be compressed to fill interstices between a first surface of the substrate and a second surface of the riding heatsink. The compressible sliding thermal interface may protrude from the first surface of the substrate such that insertion of the pluggable optical module into a cage compresses the compressible sliding thermal interface to achieve a threshold thermal boundary resistance.

Abstract: A micro-electro-mechanical system (MEMS) device may include a mirror structure suspended from a first hinge and a second hinge that are arranged to enable the mirror structure to be tilted about a tilt axis. The mirror structure may include a first actuator and a second actuator located on opposite sides of the tilt axis. The MEMS device may include a fixed electrode coupled to first actuator to cause the mirror structure to tilt about the tilt axis in a first direction based on a fixed voltage applied to the fixed electrode. The MEMS device includes a driving electrode coupled to the second actuator to cause the mirror structure to tilt about the tilt axis in a second direction opposite from the first direction based on a driving voltage applied to the driving electrode.

Abstract: An optical channel monitor (OCM) may include a modulator to provide a modulation signal and a local oscillator (LO) to provide a modulated LO signal. The modulated LO signal may be created by modulating an LO signal based on the modulation signal. The OCM may include a mixer to generate a pair of mixed optical signals. The pair of mixed optical signals may be generated based on mixing the modulated LO signal and an input optical signal. The OCM may include an optical detector to provide, based on the pair of mixed optical signals, a first electrical signal corresponding to a coherent mixture of the input optical signal and the modulated LO signal. The OCM may include a synchronous demodulator to provide, based on the first electrical signal and the modulation signal, a second electrical signal representative of the optical power spectrum of the input optical signal.
