| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The performance of integrated circuits has proceeded to higher integration density and speed based on scaling law in MOSFETs. However, heat generation and signal delay in the electrical wiring layer became problems that limits the performance. To solve these problems, an on-chip optical interconnection technology was proposed. For this purpose, an ultra-low power consumption laser is required as compared with optical devices deployed in fiber communication systems. We have proposed membrane DFB / DR lasers which consist of a thin semiconductor core layer sandwiched between dielectric cladding layers. In previous works, low threshold current, high output efficiency, and high-speed operation characteristics under a room-temperature continuous-wave condition have been reported. In this paper, the Bragg wavelength detuning design was introduced to the membrane DFB / DR lasers in order to improve lasing characteristics at relatively high temperature range. From the spectrum characteristics, the detuning amount was estimated to be 53 nm for the DFB laser and 45 nm for the DR laser. As the results, more or less temperature insensitive threshold characteristic (20 ° C <T <45 °C) was obtained with the membrane DFB laser, and relatively low threshold current (< 1 mA at 90 °C) was obtained with the membrane DFB laser. | |
