Passive Integrated Optic Devices

Optical Fiber Sensors, 1988
Fiber and integrated optic sensors are gaining importance. For the new generation of integrated and fiber optic sensors the micro- and fiber-optic elements will be replaced by integrated optics. IO-technologies, applications of optical sensors and IO-elements will be discussed. Specific examples will be presented.

Polymer electro-optic devices for integrated optics

Chemical Physics, 1999
Abstract Recent advances in polymer electro-optic polymers and in fabrication techniques have made possible advances in polymer optical guided wave devices which bring them much closer to system ready. The processing of a new thermal set FTC polymer and its incorporation into a high-frequency, low-Vπ optical amplitude modulator are reviewed.

Integrated-optic grating devices for optical interconnects

Fifth Asia-Pacific Conference on ... and Fourth Optoelectronics and Communications Conference on Communications,, 1999
Coupling among multistacked optical waveguides by grating couplers is discussed for application to interchip optical interconnects. Wavelength selective contradirectional coupling among three stacked waveguides is discussed with experimental results. A new type of grating coupler is proposed and demonstrated for efficiency improvement.

Organic Integrated Optical Devices

1989
Organic and polymeric materials have emerged in recent years as promising candidates for advanced device and system applications1–4. This interest has arisen from the promise of extraordinary optical, structural, and mechanical properties of certain organic materials5–12, and from the fundamental success of molecular design13–15 performed to create new

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 ...

Nonreciprocal Devices For Integrated Optics

SPIE Proceedings, 1989
Recent development of waveguide nonreciprocal devices, i.e. , isolator and circulator, is reviewed. Two major difficulties exist for their fabrication. First, form birefringence must be overcome to obtain high TE-TM mode conversion efficiency. Secondly, both of input and output light must be either TE or TM mode.

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.
