INTEGRATED OPTICAL MONITORING SYSTEM WITH TUNABLE FILTER

摘要

An integrated optical monitoring system comprises a hermetic package and an optical bench sealed within the package. An optical fiber pigtail enters the package via a feed-through to connectto and terminate above the bench. A tunable filter is connected to the top of the bench and filters an optical signal transmitted by the fiber pigtail. A detector, also connected to the bench, detects the filtered signal from the tunable filter. Thus, the entire system is integrated together, on a single bench within a preferably small package. This configuration makes the system useful as a subsystem, for example, in a larger system offering higher levels of functionality and optical signal processing capability.
