An initial structure design of MMI 1 × 8 optical power splitters is reported. The waveguide material is Si-based SiO2 Ge-doped and deposited by PECVD metho
A kind of fiber Bragg grating pressure sensor based on corrugated diaphragm is proposed. The relationship between the central wavelength of reflective wave of F
The heated process of raw materials for electron trapping materials (ETM) is investigated by thermo-analysis method. The temperature ranges of raw materials exp
Luminescence decay and time-resolved photoluminescence(TRPL) spectra are used for study on the transient luminescence process of the nominally disordered GaInP
