摘要： A semiconductor laser system includes a reflector on the lid that directs light emitted from the front facet to the monitoring diode. Thus, even when the diode is installed behind the semiconductor laser chip, and as a result receives back facet light, the ratio of front facet to back facet light received by the monitoring diode is increased due to the operation of the reflector. This configuration improves power tracking in Bragg grating stabilized semiconductor laser systems, for example.

摘要： A Fabry-Perot tunable filter comprises a membrane device. The membrane device includes a support structure having an optical port. Also, the membrane device has an optical membrane structure separated from the support structure over the optical port. The optical membrane structure includes a center body portion and an outer body portion. Tethers extend radially from the center body portion to the outer body portion of the optical membrane structure. The center body portion has an area that is about equal or smaller than the area of the optical port.
