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.

Integrated coefficient of thermal expansion (CTE)-flex coupler

An optical device may include an outer box. The optical device may include an inner box within the outer box. The optical device may include a heating element on a surface of the inner box. The heating element may include one or more openings. The optical device may include one or more mounting pads. A mounting pad of the one or more mounting pads may be arranged in an opening of the one or more openings and mechanically couple the inner box to the outer box through the opening.

Heater with mounting pads for mechanical, thermal, and opto-mechanical functionality

A heatsink may include a base and a plurality of fins, configured to be disposed in an air flow, that extend orthogonally from the base. The plurality of fins may have at least one of a height, an inter-fin spacing, or a thickness that varies in a direction of the air flow.

Progressive heatsink

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.

Dual thermal control element configuration for opto-mechanical assembly

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.

Isothermal enclosure with optical aperture

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.

Thermal interface for riding heatsink

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.

Optimization of heater shape for integrated heater for optical benches

A liquid crystal on substrate (LCOS) assembly may include an LCOS carrier. The LCOS assembly may include at least one thick layer on the LCOS carrier and associated with a threshold thickness. The threshold thickness may be at least 5 micrometers. The LCOS assembly may include a switching engine on the at least one thick layer. The switching engine may include an LCOS die and an LCOS cover glass to enclose an LCOS liquid. The LCOS assembly may be associated with a thermal sensitivity of less than 0.5 millidegrees of curvature per degree Celsius for a particular temperature range.
