Abstract

A tunable optical add/drop multiplexer (OADM) is demonstrated by using a micromachined 2 × 2 optical switch and a tunable fiber Bragg grating (FBG). The new hybrid OADM can be tuned to add/drop one of the multi input channels dynamically. The insertion loss of the dropped channel and added channel are 2.84 dB and 1.8 dB respectively. The transmission loss is 2.04 dB. These losses are all able to reduce greatly if the circulators are modified. The crosstalk between channels is less than -20 dB, and it can be further reduced by improving the reflectivity of FBG. The tuning speed is on the order of millisecond. The tuning range is 3.0 nm. The fabricated system is demonstrated by selectively adding/dropping one of the adjacent four channels with the spacing of 100 GHz. Systems with multi channels being dropped and / or added can be achieved by cascading the proposed structure.
