Kavli Affiliate: Eli Yablonovitch | Summary:Inverse electromagnetic design has emerged as a way of efficiently designing active and passive electromagnetic devices. This maturing strategy involves optimizing the shape or topology of a device in order to improve a figure of merit–a process which is typically performed using some form of steepest descent algorithm. Naturally, this […]

Kavli Affiliate: Eli Yablonovitch | Summary:Efficient coupling between integrated optical waveguides and optical fibers is essential to the success of integrated photonics. While many solutions exist, perfectly vertical grating couplers which scatter light out of a waveguide in the direction normal to the waveguide’s top surface are an ideal candidate due to their potential to […]
