Nonlinear Integrated Optical Devices

SPIE Proceedings, 1985
Nonlinear integrated optical devices based on second and third order nonlinearities of Ti:LiNbO3 waveguides are reviewed. Second harmonic and difference frequency generators as well as parametric amplifiers and oscillators are presented as efficient devices for frequency conversion of coherent radiation.

Optical devices integrated with semiconductor optical amplifier

Technical Digest. CLEO/Pacific Rim '99. Pacific Rim Conference on Lasers and Electro-Optics (Cat. No.99TH8464), 2003
Semiconductor optical amplifiers have been used as key optical components for high capacity communication systems. Monolithic integration is necessary for the stable operation of these devices and for wider applications. In this paper, the coupling technique between different waveguides was discussed and research results about optical devices ...

Integrated Optical lightguide device

In an integrated optical lightguide device including a light-transmitting core layer, an inclusion or buffer layer, and an active or cladding layer. The cladding layer is divided into segments. Groups of different segments exhibit different refractive indices, light intensity profiles or different degrees of sensitivity which have been effected by ...

Integrated Electro-optic Devices

1987
Integrated electro-optic devices serve the functions of rapid light modulation, time-multiplexing, signal routing, tunable filtering, and polarization conversion. They are attractive devices due to their potential applications for wide-band optical communication, optical signal processing, and sensors.

Photosensitive glass integrated optical devices

SPIE Proceedings, 1994
Photosensitive glasses for applications in integrated optical devices have recently become a popular research topic, due primarily to the success of the germania doped silica fibre counterpart. Whole ranges of devices could in principle be fabricated utilising the photosensitivity phenomenon, from directly written waveguides to more complex grating ...
