Nonlinear light mixing by graphene plasmons
D. Kundys, B. Van Duppen, O. P. Marshall +5
Graphene is known to possess strong optical nonlinearity. Its nonlinear response can be further enhanced by graphene plasmons. Here, we report a novel nonlinear electro-absorption…
Gain Modulation by Graphene Plasmons in Aperiodic Lattice Lasers
S. Chakraborty, O. P. Marshall, T. G. Folland +3
Two-dimensional graphene plasmon-based technologies will enable the development of fast, compact and inexpensive active photonic elements because, unlike plasmons in other material…
Reversible Mode Switching in Y coupled Terahertz Lasers
Owen P. Marshall, Subhasish Chakraborty, Md Khairuzzaman +2
Electrically independent terahertz (THz) quantum cascade lasers (QCLs) are optically coupled in a Y configuration. Dual frequency, electronically switchable emission is achieved in…
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…
