    Abstract: An optical bench may include an integrated heater. The integrated heater may include a substrate and a heating element disposed onto the substrate. The heating element may include at least one electrical trace. The integrated heater may be associated with a non-monolithic shape configured to cause the heating element to heat an optical device disposed in proximity to the optical bench with a temperature gradient of less than a threshold. The integrated heater may be disposed onto at least one of a surface of the optical bench or a surface of an optical component of the optical device.

    Abstract: An optical device may include an enclosure including an optical aperture and a plurality of optical components positioned within the enclosure, where the plurality of optical components are to emit and/or receive light through the optical aperture. The optical device may include at least one heating element or cooling element to provide an isothermal environment to the plurality of optical components, where the at least one heating element or cooling element is thermally coupled with the enclosure.

    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: An opto-mechanical package may include a package body having a first opening. The opto-mechanical package may include a coupler in the first opening of the package body. The coupler may have a second opening. The coupler may comprise a flexible element. A coefficient of thermal expansion (CTE) of a material of the coupler may be less than a CTE of a material of the package body. The opto-mechanical package may include a window in the second opening of the coupler. A CTE of a material of the window may be less than the CTE of the material of the coupler. The opto-mechanical package may include a first epoxy joint between a surface of the package body and a surface of the coupler. The opto-mechanical package may include a second epoxy joint between a surface of the coupler and a surface of the window.

    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 method may include identifying, by a device, a set of components of an optical device. The method may include determining, by the device, a set of design criteria based on the set of components of the optical device. The method may include identifying, by the device, an initial heater configuration based on the set of design criteria. The method may include determining, by the device, a set of optimization parameters for determining a target heater configuration based on the set of design criteria. The method may include performing, by the device and based on the set of optimization parameters, an optimization procedure to alter the initial heater configuration to determine the target heater configuration. The method may include providing, by the device, information identifying the target heater configuration based on performing the optimization procedure.
