Abstract :
Digital optical switches (DOS) are very desirable from a practical point of view because they can provide flexibility for changing polarization, wavelength, temperature, and to some extent the device geometrical parameters, without sacrificing crosstalk performance. In this paper, a new InGaAsP-InP QW tapered Y-branch digital optical switch is proposed which has been demonstrated to be fabrication-tolerant, compact, low loss, and has high speed switching capability
