Fluoride Glasses and Planar Optical Waveguides
نویسنده
چکیده
Fluoride glasses are of great interest for optical applications, as low phonon energy hosts for rare-earth ions. With an increasing need for more compact optical devices that impose higher dopant concentration, research activity has been focused on the fabrication of fluoride glass planar waveguides to produce integrated lasers and optical amplifiers, especially those based on Er3þ-doped glasses. The aim of this review is to give the state of the art of fabrication technology for fluoride glasses and to present the most interesting results obtained on confined waveguides. Recent developments in fluoride transparent glass ceramic waveguides will also be mentioned.

Chalcogenide Glass Optical Waveguides for Infrared Biosensing
Due to the remarkable properties of chalcogenide (Chg) glasses, Chg optical waveguides should play a significant role in the development of optical biosensors. This paper describes the fabrication and properties of chalcogenide fibres and planar waveguides. Using optical fibre transparent in the mid-infrared spectral range we have developed a biosensor that can collect information on whole meta...

A long with optical telecommunications systems (see box) (1-3), "integrated optics" (4) and "optical interconnect" (5) technologies are becoming more advanced. The major components of these technologies are photonic integrated circuits (PICs), optoelectronic integrated circuits (OEICs), and optoelectronic multichip modules (OE-MCMs). All the functional devices within these components, including...
متن کاملAdvances in Gallium Lanthanum Sulphide Glass for Optical Fibre and Devices
The advantages of gallium lanthanum sulphide (GLS) based glass over other competing glasses for active and infrared applications are evident through its low-phonon energy, high rare-earth solubility, high transition temperature and non-toxicity. However this glass often devitrifies during fibre drawing due to a small separation between the crystallisation and fibre drawing temperatures. Improvi...
متن کاملReactive ion etching of tellurite and chalcogenide waveguides using hydrogen, methane, and argon*
The authors report in detail on the reactive plasma etching properties of tellurium and demonstrate a high quality etching process using hydrogen, methane, and argon. Very low loss planar ridge waveguides are demonstrated. Optical losses in tellurium dioxide waveguides below 0.1 dB/cm in most of the near infrared region of the electromagnetic spectrum and at 1550 nm have been achieved—the lowes...
متن کاملHybrid Integrated Optics in Volume Holographic Photopolymer
Traditional planar lightwave circuits fabricated from lithographically-patterned waveguides in glasses, semi-conductors or polymers cannot accommodate the wide range of materials required by typical optical devices. In addition, such waveguides are nearly always defined in the material surface and thus can support only a limited density of interconnects and suffer poor performance at waveguide ...
