A new design method is proposed to optimize a heater shape in Digital Optical Switch (DOS) in order to improve the crosstalk performance. The heater has been optimized so that the thermal field distribution induce a constant effective refractive index difference (ΔNeff ) along the propagation direction. Compare to the linear heater, the result shows that the DOS using parabolic heater could improve the crosstalk performance. At temperature change of 30 °C, the crosstalk achieved by linear heater is only -10.3 dB, while the crosstalk achieved by the parabolic heater is -22.5 dB..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
