All-optical multicasting NOT and NOR logic gates using gain modulation in an FP-LD

Abstract: Abstract:We demonstrate all-optical NOT and NOR logic gates at 10 Gb/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… Show more

“…This technique provided the added advantage of supporting multicasting operation of AO-LGs with low power operation and high ER. 35 Similar realization of AO-NOT and NOR gates at 10 Gbps with FP-LDs allowing two different wavelengths was achieved with the possibility of attaining up to 40 Gbps speed by replacing with quantum-well FP-LDs. 36 A much simpler design without using any external probe signals was achieved based on a single mode FP-LD working on self-locked dominant mode to achieve NAND, XNOR, AND, and XOR operations at 10 Gbps.…”

“…SOAs require high biasing current and are expensive [15]. To overcome the higher cost and high driving current requirements, optical units such as gates and switches have been proposed using commercially available multi-mode Fabry-Pérot laser diodes (MMFP-LD) [16][17][18] and especially designed single mode Fabry-Pérot laser diodes [19][20][21]. But all these techniques require input control signal to be high for the entire period of data to be blocked at the output ports.…”

“…To overcome the requirement of high current and expensive components, a Fabry-Pe ´rot laser diode (FP-LD) may be one of the candidates for the same. Various optical units have been demonstrated using multimode FP-LD (MMFP-LD) [5], [6] and single-mode FP-LD (SMFP-LD) [7]- [9]; however, the cascading of many individual FP-LDs and the relationship between the required input power to get fully lock state and to release locking state of the SMFP-LD at given wavelength detuning have not been considered in detail.…”

“…In this paper, we analyzed input power and detuning wavelength requirements to injection-lock SMFP-LD and released SMFP-LD's locking state, and we applied those principles to demonstrate a 2 Â 4 AOAD using single-and multi-input injection-locking properties in SMFP-LD. Since SMFP-LD has self-locking mode, it does not need additional probe beam, which is required in other optical technologies [5], [6]. Hence, the proposed AOAD using SMFP-LD has several advantages such as simple in configuration, power and cost efficient, and cascadable structure.…”
