Abstract:
1. A transmitting optical sub-assembly (TOSA) comprising: a light emitting element; one or more heating elements thermally coupled to the light emitting element so as to provide a substantially constant heat generation profile and/or temperature profile across the TOSA during a light emitting element dormant period and a light emitting element firing period; a thermoelectric cooler thermally coupled with at least one of the one or more heating elements so as to provide a heat load on the thermoelectric cooler during the light emitting element dormant period and/or the light emitting element firing period; a controller operably coupled with the one or more heating elements so as to control the substantially constant heat generation profile and/or temperature profile; and one or more thermocouples thermally coupled with the one or more heating elements and operably coupled with the controller, wherein the TOSA has a constant heat generation profile and/or temperature profile with respect to the light emitting element and one or more TOSA components during the light emitting element dormant period and the light emitting element firing period.
