We present a silicon nitride (SixNy) arrayed waveguide grating (AWG). Crosstalk in this AWG was reduced by decreasing the phase error in a multimode arrayed waveguide (WG) at center wavelength of 838 nm. 8-channel SixNy AWGs using arrayed WGs with do

We herein report the preparation of a soluble polyimide from a photoreactive diamine and a phenolic diamine, to which electro-optic (EO) properties were imparted by the introduction of an EO chromophore (Disperse Red 1) into the phenolic group of the

This brief presents a single-ended asymmetric push-pull inverter for driving a vertical-cavity surface-emitting laser (VCSEL). The proposed driver topology features less power dissipation compared with commonly used differential CML-based drivers. Co

We investigated silicon nitride(SixNy) arrayed waveguide grating (AWG) with multimode arrayed waveguide at 850nm wavelength to reduce phase error due to the sidewall roughness of the waveguide. The fabricated 8-channel SixNy AWG shows low crosstalk o
