Abstract
The enhanced electro-optic coefficient of phase modulators employing InGaAsP/InP three-step quantum wells (3SQW) was reported. Structural and optical properties of the epitaxial layers were characterized with high-resolution x-ray diffraction and photoluminescence techniques. Enhanced δn/δV combined with an optical absorption coefficient below 1 cm -1 led to ∼36 times higher figure of merit, and nearly one order of magnitude lower power consumption in the modulator. These properties make 3SQW an ideal candidate for high-power, low-drive voltage MZ modulators required for high performance analog radio frequency link applications.
