Design and Fabrication of on-chip Midinfrared Emitter and LVOF

In this thesis,two essential parts of microspectrometer are designed, fabricated and measured. They are a hot wire of polysilicon with constant temperature profile that used as the IR light source, and the LVOF which is aimed at IR spectral range. In order to have the desired IR source, the hot wire should have temperature distribution as...

Microstructure for Mid-Infrared Spectroscopy for Biofuel Composition Measurement

Biofuel sensors for measuring the ethanol and gasoline concentrations in bio-ethanol blends, have been studied worldwide and currently used in engine management in FlexFuel cars fabricated by amongst others, Ford Motor Company. However, water that results from ethanol sugar cane is inevitable present in the ethanol blend and requires a sensor...
