| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, resistor-capacitor (RC) delay and heating in electrical wiring caused by miniaturization of elements in large scale integrated (LSI) circuits have become non-negligible, optical interconnection is expected as one of candidates to solve these problems. We have proposed a semiconductor membrane laser as a light source for on-chip optical interconnection. Since the semiconductor membrane laser consists of thin semiconductor core layer sandwiched between very low refractive-index cladding layers, an extremely low threshold current operation by strong optical confinement is expected. In this paper, we analyzed power consumption of semiconductor membrane distributed-reflector (DR) laser which can realize high efficiency and low power consumption operation. As a result, it was found that power consumption by Joule heating becomes dominant due to high device resistance when the cavity length becomes shorter, and the optimal cavity length which gives the minimum power consumption exists if we assume required conditions (i.e. output power and direct modulation speed) for a light source. In the case of adopting low resistivity of 0.035 $Omega$$cdot$cm ($N_A$ = 4 $times$ $10^{18}$ $cm^{-3}$), the minimum energy cost was estimated to be 37 fJ/bit at the cavity length of 17 $mu$m. Toward further reduction of the energy cost, reductions of waveguide loss and coupling loss between each device will be effective. | |
