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.
Claims20
An optical bench, comprising:
- an integrated heater,
- the integrated heater comprising:
- a substrate;
- and
- a heating element disposed onto the substrate,
- the heating element comprising at least one electrical trace,
- wherein the integrated heater is 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,
- wherein the integrated heater is disposed onto at least one of a surface of the optical bench or a surface of an optical component of the optical device.
A heater, comprising:
- a plurality of heating elements disposed onto an interior surface of an optical package without an adhesive layer being disposed between the plurality of heating elements and the interior surface of the optical package,
- the optical package to enclose an optical device,
- the plurality of heating elements being arranged in a shape to provide an isothermal environment inside the optical package;
- and
- wherein the isothermal environment comprises a temperature gradient of less than 3 degrees Celsius.
An optical package, comprising:
- a wavelength selective switch (WSS) disposed on an optical bench inside the optical package;
- and
- a plurality of heaters,
- wherein at least one heater, of the plurality of heaters, is disposed on the optical bench inside the optical package without an adhesive layer disposed between the at least one heater and the optical bench,
- wherein at least one heater, of the plurality of heaters, has a shape to enable the plurality of heaters to maintain an isothermal environment for an ambient temperature range of between 0 degrees Celsius and 60 degrees Celsius,
- wherein the isothermal environment comprises a temperature gradient inside the optical package of less than 3 degrees Celsius.
