Notes:
The phase modulation of asymmetric quantum-well embedded waveguides is studied. In order to accurately analyze the modulation from quantum wells and optimize the performance of waveguide modulators, a transfer-matrix method is developed to calculate the bias-controlled phase modulation of waveguides with an arbitrary refractive index distribution. The refractive index change may include those from free-carrier effects and the nonlinear effects of bulk material and quantum wells. The linear electro-optic effect introduced by asymmetric quantum wells can potentially be used to improve the frequency performance of semiconductor waveguide phase modulators.
