We experimentally demonstrate a novel multiwavelength continuous wave (CW) optical source with precise 25-GHz spacing based on the longitudinal mode-carving of a supercontinuum (SC) spectrum. The CW light was modulated with a 10-Gb/s non-return zero (NRZ)
A laser power feedback control system that features fast response, large-scale performance, low noise, and excellent stability is presented. Some essential points used for optimization are described. Primary optical lattice experiments are given as exampl
A transparent and emitting ceramic of Y2O3 doped with 6% Tm3 ions is fabricated by vacuum sintering with ZrO2. Absorption, photoluminescence (PL), and PL excitation (PLE) spectra are investigated in a spectral range of 200 to 2 100 nm at various temperat
