【 摘 要 】

References(6)Cited-By(4)We demonstrate all-optical NOT and NOR logic gates at 10Gb/s based on gain modulation of a transverse electric (TE) polarized light in a Fabry-Perot laser diode (FP-LD). An FP-LD shows a gain for a TE-polarized injected probe beam. The gain can be modulated by injection of a pump beam. Using the gain-modulation characteristic, we implemented all-optical NOT and NOR logic gates. We investigate double channel out performances as an example of the multicasting function of the gates. We measured around 1.5dB power penalty at a bit-error-rate of 10-9 and observed over 12dB extinction ratio in each of the gate operation.
