Paper Abstract

We describe the fabrication of a 2×2 port optical device based on a thin film filter, and also newly propose a 4-channel optical add drop multiplexer (OADM) module using these devices. The optical performance of the proposed OADM module is evaluated theoretically and experimentally, and compared to that of the typical OADM modules using 1×2 port optical devices for 4, 8, 16, and 32 drop channels. Since the 2×2 port optical device accomplishes the function of wavelength multiplexing and demultiplexing simultaneously in the proposed OADM module, the insertion loss of through channels can be improved by 1.2 dB compared with that of a typical OADM module using 1×2 port optical devices. In addition, both the size and price of the module can be reduced by ~40 to 50%.
