편광특성이 배열 도파로 소자의 Crosstalk에 미치는 영향

2001년도 한국전기전자재료학회 춘계학술대회논문집, 디스플레이 광소자분야, pp. 79-82, 470 (2001. 4. 21). *** 서울 광운대학교 An arrayed-waveguide grating multiplexer with raised structure is fabricated in order to effect polarization sensitivity. Since polarization is usually not known after propagation in an optical fiber, passive WDM components such as monolithic wavelength demultiplexer have to be polarization insensitive. Here, we observed that polarization have effect on crosstalk of output spectrum in arrayed-waveguide grating. First, we achieved the fabrication and characterization of arrayed waveguide gratings using sol-gel derived silica glass films formed on fused silica substrates. The wavelength shift in the transmittance curve is about 2.09nm, and the measured crosstalk was below 12 dB for all channels.
