Single-wavelength distributed feedback (DFB) lasers are widely used in high-speed access networks; however, the device yield is generally low due to threshold degeneracy resulting from uniform periodic gratings. In this work, we propose and experimen

We demonstrate DFB lasers with a holographic-generated two-layer moire grating. The resulting DFB lasers exhibit stable single wavelength operation $(> 40\ dB$ SMSR) at its Bragg wavelength and superior static and dynamic device performance.

An InGaAs buried-heterostructure photodetector (BH-PD) was proposed and fabricated. By introducing etching and refilling with large bandgap and lower concentration semi-insulating InP, it was found that we can reduce the capacitance of P-I-N PDs by 3

A SiN x /SiO x multi-inorganic barrier shows a low water-vapor transmission rate (WVTR) as the SiN x /SiO x pairs increased to five pairs. We found that the WVTR can be significantly reduced after coating a polymer overcoat on the barrier with five S
