Study of Subwavelength Gratings to Understand Their Polarization Behaviour

M. G. Sridharan[1], A. Prabhakar[2], and S. Bhattacharya[2]
[1]Photonics Group, Department of Electrical Engineering, Indian Institute of Technology Madras, Chennai, India
[2]Department of Electrical Engineering, Indian Institute of Technology Madras, Chennai, India

Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the ... Read More

Optimization of a High-Temperature High-Pressure Direct Wafer Bonding Process for III-V Semiconductors
