IOO Assignment Integrated Optical Microsystems Group (IOMS) Optical Loss Spectra with Prism Coupling Technique
 

Summary: IOO Assignment Integrated Optical Microsystems Group (IOMS)
Optical Loss Spectra with Prism Coupling Technique
Introduction
In the field of photonics the notion of planar integration has become more and more
important. It offers potential technological and economic advantages providing compactness
by reducing many critical devices down to single chip dimensions. The material systems used
in the field of integrated optics are best characterized optically by making use of the prism
coupling method. It can provide accurate information on the refractive index, thickness and
optical losses of the waveguides. Among these, it is of great important to be able to measure
the optical losses as a function of wavelength.

Project Description
Presently the experimental setup for optical loss measurements is readily available. The
aim of this IOO assignment will be to optimize the setup and measure reliably the optical
losses of various planar waveguides based on material systems such as Al2O3, etc., as a
function of wavelength. The results will be verified by making loss measurements using
another prism coupling setup and employing lasers at various wavelengths, instead of the
white light source. The student involved will have an opportunity to interact closely with our
experienced staff during his/her research. If you are interested please feel free to contact us
for further discussion.
