| Research Abstract |
1. Establishment of all-opticallogic gate devices: On the semiconductor-optical-amplifier-integrated Mach-Zehnder interferomator all-optical gates (SOA-MZI), we have reduced propagation loss significantly by improving fabrication techniques of high-mesa waveguides and by introducing low dope cladding layers. Then, concerning the all-optical logic gate device based on active multimode couplers (MMIs), we have developed a new model and a simulation tool to analyze cross phase modulation between optical pulses.
2. Establishment of all-optical flip-flops: Regarding the all-optical flip-flop of MMI bistable laser diode (BLD) type, for the sake of obtaining single-longitudinal mode operation and cascadability, we fabricated devices incorporating distributed Bragg reflectors (DBRs). As a result, we could achieve complete single longitudinal mode oscillation with a 23dB side-mode suppression ratio as well as a broad operation wavelength range of 1520-1570nm and a high switching extinction ratio
… More
of 26dB. Dynamic characterization with 10ns input optical pulses revealed good performances, such as 16dB dynamic extinction ratio, 320ps rise time, 470ps fall time, and a dynamic operation wavelength range of 1540-1570nm. Furthermore, the introduction of a tensile strained quantum well active layer resulted in a 16dB extinction all-optical flip-flop operation which is completely independent of polarization.
3. Analysis and design of a digital all-optical integrated circuit prototype: We constructed a fundamental all-optical packet processing circuit consisting of the all-optical logic gate and the all-optical flip-flop, and conducted wavelength-multiplexed packet routing demonstration by all-optical processing. Consequently, penalty-free all-optical switching with 320Gbps throughput (40Gbps X 8 lambda) has been realized.
4. Integratable optical non-reciprocal devices: An optical waveguide isolator of non-reciprocal loss type that can be operated at high temperatures has been developed by utilizing ferromagnetic MnSb. Good characteristics including isolation ratio of 6.0dB/mm, insertion loss of 4.9dB/mm, and a temperature range of 20-100℃ have been demonstrated. Less
