Multi‐Octave All‐Dielectric Directional Coupler Using Integrated Half‐Mirror for Ultrawideband Terahertz Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...

Large Beam Size Grating Coupler in Silicon‐on‐Insulator Using Fully Etched Subwavelength Gratings

open access: yesLaser &Photonics Reviews, EarlyView.
A fully etched, double‐period subwavelength structure is used to design a silicon‐on‐insulator grating coupler for large, well‐collimated off‐chip beams. The work experimentally demonstrates the generation of a 350‐micron wide beam, with a 54% radiation efficiency, thereby enabling efficient interaction with targets centimeters away from the chip ...
