Summary on Grant Application Form |
|
ODS will be a bi-directional element linking the MEMS filter and the Bragg Grating sensors that form part of the strain detection system. Thus the ODS will accept an optical signal, and distribute it to the eight fibres containing the sensors. It will also receive the return signal from the sensors, and interface to detectors. This is a large integration operation interfacing to up to 20 fibres. Therefore it will be one of the largest circuit integrations yet undertaken in this emerging technology. Alignment between waveguides be via V-grooves, and detectors may be either on or off-chip.The Optical Delivery System will contain a reference Fabry-Perot cavity operated in transmission. The most serious problem will be the thermal stability. Since silicon has a large thermo-optic coefficient of 1.86 x 10-4/Kelvin, the cavity would best be formed in air. The optimum design will require modelling of the entire thermal environment, which will be carried out via finite element processing. Should it not be possible to provide sufficient stability via thermal design, environmental control will be used. Since resolution of the wavelength to fractions of a picometre is required, the thermal control of the cavity is an enormously demanding problem, and hence the design and modelling process is a vital step in this process.
