| The large-scale ex tensible thermo-optic and electro-optic controlling circuits with the output voltage ranges of 0－10V and 0－2V (tuning resoluti on of 10mV) are designed respectively,in order to compensate for the fabrication error and drive the optical switch elements of 16×16integrat ed optical switching chip.We describe the control process of the 16×16integrated optical switching chip,which is composed of Mach-Zehn der interference (MZI) switch elements.A modified looping algorithm to route data based on the optical switching performance is proposed,which can be applied for the cases with deterioration or partial failure of the switch ing elements.We set up the test platform for the silicon-based integrated photonic switching chip with the modified looping algo rithm,and the measured results show that the insertion loss and crosstalk of the chip module are below 33dB and －10dB,respectively, which meet the requirement for error-free transmission in optical communication system. |
