  • Heretofore, it was enough that most of optical transceiver modules for automotive networks have the performance of data rate from 10 Mbps to 150 Mbps. As the required data rate in automotive infotainment systems has recently been increasing, the development of a new optical transceiver having high speed data rate over 1Gbps is now required. Therefore, we suggested a next-generation bi-directional optical transceiver module using vertical cavity surface emitting laser technology and plastic clad fiber technology, for the next-generation automotive optical network, MOST1000. We fabricated the high-speed and compact optical transceiver having 1 Gbps data rate and -22 dBm sensitivity satisfying bit error rate $10^{-12}$.

  • We demonstrate a novel OFDR system with compactness and short measurement time based on the use of a wavelength-swept mode-locked fiber laser. The optical source uses an intra-cavity tunable Fabry-Perot filter as a tuning element. The fiber laser sweeps 20 nm in less than 10 ms. Spatial resolution of 100 fm and total measurement range of several centimeters are demonstrate

  • 최근 레이저 분광학에 있어서 고감도 분광법으로 알려져 있는 주파수 변조 분광법(frequency modulation spectroscopy)과 레이저 광 주파수 안정화 응용에 대한 원리와 특징을 살펴본다. 또 super-cavity을 이용한 단일모드 He-Ne 레이저를 사용하여 FM 분광신호를 검출하고 그 신호특성에 대하여 기술하였다.
