Abstract :
This paper analytically derived the optimum condition of coupling efficiency for the lossy double ring resonator. Using this condition, a new concept of nonblocking wavelength switch using a series-coupled ring resonator is proposed. The crosstalk characteristics of the wavelength switch were investigated using the transfer matrix. Using this optimum condition, the crosstalk of the wavelength switch can be reduced.
