Y coupled terahertz quantum cascade lasers
Owen P. Marshall, Subhasish Chakraborty, Md. Khairuzzaman +2
Here we demonstrate a Y coupled terahertz (THz) quantum cascade laser (QCL) system. The two THz QCLs working around 2.85 THz are driven by independent electrical pulsers. Total pea…

Longitudinal Computer Generated Holograms for Digital Frequency Control in Electronically Tunable Terahertz Lasers
Subhasish Chakraborty, Owen P. Marshall, Md. Khairuzzaman +2
A transverse computer-generated hologram (CGH) diffracts and provides flexible control of incident light by steering it to any point in the projected image plane - i.e. CGHs are ab…
