摘要： An optical functional waveguide having a small size, used with saved energy, controlling the phase of light at high speed, and adjusting the optical path length. The optical functional waveguide comprises a substrate (11), a quartz waveguide clad (12), a quartz waveguide core (13), groove structures (14), a filling material (15), and heater electrode (16). The filling material (15) placed in the groove structures (14) is, e.g., a resin transparent to the wavelength region of the guided light, and the refractive index temperature coefficient is about 10 to 100 times that of quartz. The heater electrode (16) is interposed between the groove structures (14) provided along the optical path. Therefore, the temperature of the filling material (15) can be varied sharply and quickly with small energy.

摘要： An optical disc player enters a sleep (low power consumption) mode when inactive for a predetermined time. The optical disc player includes a buffer RAM for storing index information read from a disc. A refresh circuit is connected to the buffer RAM to refresh the RAM. The refresh circuit includes a reference clock generator which generates a reference clock signal having a predetermined frequency from a reference clock using an oscillator. When the disc player enters the sleep mode, it issues a stop signal to the reference clock generator, which then stops generating the reference clock signal and produces a sleep mode clock signal having a frequency necessary to refresh the buffer RAM. A refresh signal generator circuit connected to the reference clock generator produces a refresh signal for the buffer RAM using the sleep mode clock signal. A control circuit connected to the refresh circuit produces the stop signal when it receives a sleep command and deactivates the stop signal when it receives a recovery command. Since the oscillator is stopped during the sleep mode, the disc player dissipates very little power in the sleep mode.

摘要： A CD-ROM decoder for decreasing the load on a microcomputer. The CD-ROM decoder stores in a buffer memory in sector units digital data. The CD-ROM decoder includes a check head register for storing a first address of the buffer memory when storing the processed digital data in the buffer memory. A check sector counter counts the number of sectors of the processed digital data stored in the buffer memory to generate a count value. A command decision circuit decides whether digital data requested to be transferred is stored in the buffer memory based on the first address, the count value, and a head address of the digital data. The command decision circuit permits the CD-ROM decoder to transfer the processed digital data when deciding that the digital data requested to be transferred is stored in the buffer memory.

摘要： An optical signal processing apparatus includes a first optical waveguide and a first slab waveguide configured to equally distribute an output light of the first optical waveguide. A first arrayed waveguide includes an aggregate of optical waveguides changing in optical length by a constant interval for dividing the output light. A second slab waveguide focuses the optical output of the first arrayed waveguide. A spatial filter receives incident light focused by the second slab waveguide and distributes the incident light on a straight line. The spatial filter also modulates the light into a desired amplitude according to the position on the straight line. The apparatus also includes a second arrayed waveguide and an aggregate of optical waveguides changing in optical length by a constant interval for applying light modulated by the spatial filter to the second arrayed waveguide. Structure is provided for converging the output light of said second arrayed waveguide to a single point. The resulting output light is then appiled to a second optical waveguide.
