    摘要： Provided is a mode converter for use in optical communication. The mode converter includes a first waveguide, a second waveguide optically coupled into the first waveguide, and omnidirectional reflectors that are disposed on either side of the first waveguide and have forward reflectivity with respect to a mode propagating in the first waveguide. The mode converter provides minimum loss coupling between either optical fiber or low index difference waveguide and a high index contrast waveguide. Furthermore, the mode converter achieves high, bi-directional optical coupling over a wide wavelength range with a simple manufacturing process.

    摘要： An optical isolator using a photonic crystal. The optical isolator includes an input portion that in turn includes an input waveguide part and an input waveguide having a taper portion formed in the input waveguide part. An output portion includes an output waveguide part and an output waveguide formed in the output waveguide part continuously with the input waveguide. The output waveguide includes a backward directional optical signal shield surface having an inclination greater than the taper portion with respect to an optical signal transmission center axis. The optical isolator is operable to have an optical signal substantially transmitted in a forward direction from the input portion to the output portion and further operable to substantially not transmit the optical signal in a backward direction from the output portion to the input portion.

    摘要： An image stabilizer of a camera is provided that can compensate for the effects of the shaking of a main body that includes a lens, in real-time, by using an optical element. The image stabilizer includes: an optical element that can be tilted, which is installed on an optical path, which transmits light and which tilts to shift the transmitted light to compensate for the optical path; a sensor provided near the main body, which senses the shaking of the main body; a calculating unit which receives a sensing signal from the sensor and calculates the necessary tilt angle of the optical element; and an actuator which drives the optical element according to the result output from the calculating unit. The image stabilizer can sense the shaking of the main body in real-time and prevent shifting of the image formed on an image forming surface.
