Advanced data centers require high throughput I/O processing for servers and storage devices connectivity. Silicon photonics technology offering low-cost, low-power, and high-performance is a promising solution for interconnection applications. In this talk, we will review the latest progress of the highly integrated Silicon photonics devices for 4×25 Gb/s active optical cables and transceivers. This...
We report planar integration of tapered Terahertz (THz) quantum cascade lasers (QCLs) with spoof surface plasmon (SSP) structures. The SSP structure consists of one plasmonic coupler and periodically arranged scatters. The resulting surface-emitting THz beam is highly collimated with a beam divergence as narrow as 3.6°×9.7°. As the beam divergence is inverse proportional to the light emission area,...
<para> This paper investigates the heat conduction behavior of a terahertz (THz) quantum-cascade laser (QCL) active region by measuring its temperature using in-situ microprobe band-to-band photoluminescence (PL) technique. The heat resistance of different regions in QCL structure is derived from the temperature measurement. Experimental results show that thinning the substrate from 300 ...
