We suggest a compact and efficient duplexer using the multimode interference (MMI) effect and the extraneous self-imaging phenomenon for gigabit-capable passive optical network and gigabit Ethernet passive optical network applications. To experimentally evaluate the suggested duplexer, silica-based MMI couplers were tested using light sources with wavelengths of 1310 and 1490 nm . From the ex perimental results, this device showed relative output powers of 0.3 and 0.7 dBm for the light sources with 1490 and 1310 nm wavelengths, respectively. The return power was measured to be less than 40 dBm .
