The combination of nanofabrication techniques, laterally coupled micro-ring -resonator modulator design, angle multi-mode interference couplers, and highly efficient InP-based modulator materials, were studied to demonstrate wavelength selective modulator arrays. A low-capacitance self-aligned electrode current was employed to permit high-speed modulation of 1-μm-wide waveguide ridges possessing low capacitance. High-aspect-ratio ridges are formed by Cl/Ar/H inductively coupled plasma reactive ion etching with wall roughness of a few nm. Digital modulation at 1 GHz shows good sensitivity of 600 mV peak-to-peak.
