Hexagonal Transverse Coupled Cavity VCSEL Redefining the High-Speed Lasers
Elham Heidari, Hamed Dalir, Moustafa Ahmed +2
The vertical-cavity surface-emitting lasers (VCSELs) have emerged as a vital approach for realizing energy efficient, high speed optical interconnects in the data center and superc…
Extra Loss-free Non-Hermitian Engineered Single Mode Laser Systems
Mohammad H. Teimourpour, Hamed Dalir, Elham Heidari +4
In a laser system non-Hermitian methods such as Parity-Time (PT) Symmetry and Supersymmetry (SUSY) have shown and demonstrated the ability to suppress unwanted lasing modes and, th…
Selective Near Perfect Light Absorbtion by Graphene Monolayer Using Aperiodic Multilayer Microstructures
Iman Zand, Hamed Dalir, Ray T. Chen +1
We investigate 1D aperiodic multilayer microstructures in order to achieve near total absorption in preselected wavelengths in a graphene monolayer. Our structures are designed by…
Plasmonic Optical Modulator based on Adiabatic Coupled Waveguides
Rui Wang, Hamed Dalir, Xiaochuan Xu +4
In atomic multi-level systems, adiabatic elimination is a method used to minimize complicity of the system by eliminating irrelevant and strongly coupled levels by detuning them fr…
Design of Highly Efficient Hybrid Si-Au Taper for Dielectric Strip Waveguide to Plasmonic Slot Waveguide Mode Converter
Chin-Ta Chen, Xiaochuan Xu, Amir Hosseini +4
In this paper, we design a dielectric-to-plasmonic slot waveguide mode converter based on the hybrid silicon-gold taper. The effects of mode matching, the effective index matching,…
Low-loss mode converter for coupling light into slotted photonic crystal waveguide
Xingyu Zhang, Harish Subbaraman, Amir Hosseini +4
We design, fabricate and experimentally demonstrate a highly efficient adiabatic mode converter for coupling light into a silicon slot waveguide with a slot width as large as 320nm…
