Sensitivity analysis sub-wavelength optical gratings
2015/8/6
Numerical optimization of photonic devices is often limited by a large design space: the finite-differences gradient method requires as many electric field computations as there are design...
Optical Gratings for Electronic Controllable Wavelengthsensitive Switches on Si/SiGe Heterostructures
Optical Gratings Wavelengthsensitive Si/SiGe Heterostructures
