摘要:
A method of attaching a wafer by suction, includes a step of mounting a wafer on a right arm and a left arm of a transfer jig, moving the transfer jig toward a wafer suction stage in such a manner that a facing right arm surface of the right arm slides along and in contact with a first side surface of the wafer suction stage and a facing left arm surface of the left arm slides along and in contact with a second side surface of the wafer suction stage until the wafer comes to lie directly above a mounting surface of the wafer suction stage, mounting the wafer on the mounting surface by moving the transfer jig downward toward the wafer suction stage while maintaining the contacts, and attaching the wafer to the mounting surface by suction.

摘要:
A light-controlled light modulator can achieve high-speed, low-loss wavelength conversion. Continuous light with a wavelength &lgr;j is launched into an MMI coupler via a port, and is split into two parts by the MMI coupler, which are led to a loop-type interferometer. In the loop-type interferometer, the two parts travel separately around the loop as clockwise traveling light and counterclockwise traveling light, are combined by the MMI coupler again via a filter-equipped phase modulator, thereby being emitted to the port. In this state, signal light &lgr;i(s) with a wavelength &lgr;i is launched into the filter-equipped phase modulator via a port. Even when the wavelength &lgr;i of the signal light &lgr;i(s) is equal to the wavelength &lgr;j of the wavelength converted output light, the wavelength conversion can be achieved with preventing noise from being mixed into the output light emitted from a port.
