Abstract

The invention is a tunable wavelength selecting / locking optical dense wave division multiplex wave combining / separating device, including an input port and eight wave separation output ports, two wavelength tuning selection combining components, and the wavelength locking control structure includes optical-fiber coupler, optical FP etalon, fast wavelength tuning filter, two fast photoelectric conversion probes, and differential amplifier tracking signal processor. The wavelength locking control structure collects and processes two optical signals of a primary optical path and controls the wavelength tuning selection combining components in the primary optical path by circuit feedback. The wavelength tuning selection combining components are packaged with many optical resonance cavities in parallel on an optical shared surface, adopt the electrooptical effect of electrooptical polymer film and the multi-reflection coherence theory of optical resonance cavities to form tuned filtering characteristic, making the output of each wave separation port of the multiplexer meet the design requirements on wavelength selection and wideband tuning, and it makes locking control on the central wavelength of each channel, stable and reliable.

Description

technical field

[0001] The invention relates to a 1*N tunable wavelength selection / locking optical dense wavelength division multiplexer / demultiplexer, and the fast optical switching matrix formed by it can be applied to optical burst switching and optical packet switching. It belongs to the technical field of optical communication. Background technique

[0002] The next-generation optical network oriented to Internet services begins to develop from IP over SONET / SDH (Internet Protocol Access Optical Synchronous Digital Network) to IP over WDM (Internet Protocol Access Wavelength Division Multiplexing System) network. IP over WDM, also known as optical Internet, means that IP is directly connected to the WDM network or directly connected to the optical fiber. IP network puts forward higher and higher requirements for optical transmission and optical switching bandwidth.

[0003] In the past few years, the core equipment for building an all-optical network is optical downst...
