High-Responsivity Planar Photodetector Based on Methylammonium Lead Bromide Perovskite Thin Film

open access: yesPhotonics, 2023
We have fabricated planar interdigitated photodetectors exhibiting high responsivity. These detectors are based on thin layers of methylammonium lead bromide (MAPbBr3) at 90 nm thickness. MAPbBr3 thin films were first characterized on glass (borosilicate)

Enhancing the photomixing efficiency of optoelectronic devices in the terahertz regime [PDF]

open access: yes, 2006
A method to reduce the transit time of majority of carriers in photomixers and photo detectors to $< 1$ ps is proposed. Enhanced optical fields associated with surface plasmon polaritons, coupled with velocity overshoot phenomenon results in net decrease

Optimization of photomixers and antennas for continuous-wave terahertz emission [PDF]

open access: yes, 2005
We have studied terahertz emission from interdigitated finger photomixers coupled to planar antenna structures. Using both pulsed and continuous-wave excitation, polarization measurements reveal that the antenna design dominates the properties of the
