Wavelength flattened characteristics and excellent branching uniformity less than 0.4 dB have been achieved in wavelength range from 1200 nm to 1700 nm.展开更多
The trends of fiber-based optical component technologies are reviewed focusing on fused-taper couplers and fiber Bragg gratings for high bit-rate DWDM transmission systems.
We have developed a subminiature gain flattening filter with the 90% volume reduced package compared with conventional ones. The excellent thermal stabilities for the transmission characteristics of 0.0002dB/℃and 0.6...We have developed a subminiature gain flattening filter with the 90% volume reduced package compared with conventional ones. The excellent thermal stabilities for the transmission characteristics of 0.0002dB/℃and 0.67pm/℃, and the high power durability up to 1 W were confirmed.展开更多
