Abstract
A PLC-type pump combiner has been developed, which is capable of multiplexing for 15 wavelength channels between 1410 and 1510 nm, thereby making it applicable to Raman amplifiers and high-power optical amplifiers for dense wavelength division multiplexing (DWDM) systems. Our device has a narrow spectral pass-band spacing of 1 THz, milan米兰体育官网 total insertion loss below 2.0 dB. Both input and output connections between PLC and fibers are physical contact (PC) with a mechanically transferable (MT) connector-like structure milan米兰体育官网re adhesive free in the optical path, so they show good stability for a high input power more than 1.2 W.
