摘要： An object is to provide an optical device capable of relaxing a manufacturing condition for an optical waveguide used in the optical device.
An optical device 500 is provided with an optical waveguide 200 including a core and a cladding optically joined together, and a temperature controller 600 that controls temperature of the optical waveguide, wherein the optical waveguide includes the core and the cladding formed such that a normalized frequency specified for light propagating through the optical waveguide changes across a cutoff frequency of a guided mode determined from a structure of the optical waveguide in a temperature range in which a refractive index of the core is higher than a refractive index of the clad. The temperature controller controls the temperature of the optical waveguide over a temperature range across temperature at which the normalized frequency equals to the cutoff frequency.

摘要： Disclosed is a laser light transceiver which is configured so as to include a polarization changing unit 2 for outputting a laser light beam outputted from a transmission light source 1 toward a direction corresponding to the polarization of the laser light beam while changing the polarization of the laser light beam with respect to time. As a result, the laser light transceiver can transmit a laser light beam, whose power is not decreased, in two eye directions without mechanically scanning with the laser light beam.

摘要： Plural signal beams enter a planar waveguide laser amplifier from different directions to follow different paths therein, which reduces a region not contributing to amplification where no signal beam passes. Plural signal beams follow different paths in the planar waveguide, and a second signal beam utilizes the gain of a portion of the planar waveguide that a first signal beam cannot utilize. By this configuration, a region not contributing to amplification of the signal beams in the planar waveguide laser amplifier can be reduced, causing to efficiently amplify plural signal beams.
