Single-mode conditions for Ga(x)In(1-x)As(y)P(1-y)/InP double-heterostructure strip waveguides with Ga(x')In(1-x')As(y')P(1-y') side bounding layers.
Single-mode guiding conditions are determined by using the effective-index method for Ga(x)In(1-x)As(y)P(1-y)/InP waveguides having Ga(x')In(1-x')As(y')P(1-y') side bounding layers.
