Photonic Devices - Bragg gratings This graph shows typical experimental & theoretical Grating reflection spectra. The peak wavelength is sensitive to changes in temperature (0.01nm/ degree C) as well as changes in strain (0.001 nm if the fibre stretches by 1 part in 10 6 ), making Bragg gratings useful in fibre sensors. Theory Experiment Peak shifts with temperature and / or strain Reflectivity (%)

Planar Optical Waveguides Planar waveguides can also be built up layer by layer, as has been done for silicon chips Sequence of processing steps: Cladding deposition Core deposition Masking Etching Cladding deposition This allows quite complex waveguide structures to be fabricated over a large area in a short time Microscope photo of a buried channel waveguide showing the ~ 6 micron core (bright) against a darker cladding

Microphotonics - a new frontier Micro-electro-mechanical systems (MEMS) In recent years, new kinds of moving objects such as tiny motors, pumps and moving mirrors have been fabricated on micrometer scales. This tiny electronically tiltable mirror is a building block in devices such as all-optical cross-connects and new types of computer data projectors. MEMS array configured as an optical crossconnect
