High efficiency THz photodetectors
نویسندگان
چکیده
We present a review of our latest work on UniTravelling Carrier Photodiodes for high efficiency THz emission. The detectors’ waveguide structure allows for both higher responsivity and saturation power thus achieving the highest published THz figure of merit (PTHz/Popt ) up to 1.5 THz for such devices. We also discuss new material development using solid source MBE and the possibility of monolithic integration within a photonic heterodyne source. Keywords—Optical Heterodyne Generation (OHG), Terahertz, Traveling Wave Photodiode (TW-PD), Uni-Traveling Carrier Photodiode (UTC-PD).

High Speed Velocity-Matched Distributed Photodetectors
In the last few years, remarkable progress has been made in ultrafast, and high-speed, high power photodetectors, as reviewed in [ 1,2]. In terms of applications, the high-speed photodetectors can be divided into four general different categories: (1) high-speed digital communication systems, (2) RF photonic systems, (3) ultrafast optoelectronic sampling, and (4) optoelectronic generation of mi...
متن کاملPlanar integrated metasurfaces for highly-collimated terahertz quantum cascade lasers
We report planar integration of tapered terahertz (THz) frequency quantum cascade lasers (QCLs) with metasurface waveguides that are designed to be spoof surface plasmon (SSP) out-couplers by introducing periodically arranged SSP scatterers. The resulting surface-emitting THz beam profile is highly collimated with a divergence as narrow as ~4° × 10°, which indicates a good waveguiding property ...
متن کاملWarping effect-induced optical absorbance increment of topological insulator films for THz photodetectors with high signal-to-noise ratio.
Strong optical absorbance makes topological insulator (TI) surfaces a promising high-performance photodetector in the terahertz (THz) to infrared frequency range. Here, we study the optical absorbance of more realistic TI films with hexagonal warping effect using the Fermi's golden rules. It was found that when the warping term is λ ≠ 0, the absorbance is no longer a universal value as that of ...
متن کاملTowards photodetection with high efficiency and tunable spectral selectivity: graphene plasmonics for light trapping and absorption engineering.
Plasmonics can be used to improve absorption in optoelectronic devices and has been intensively studied for solar cells and photodetectors. Graphene has recently emerged as a powerful plasmonic material. It shows significantly less loss compared to traditional plasmonic materials such as gold and silver and its plasmons can be tuned by changing the Fermi energy with chemical or electrical dopin...
متن کاملGeneration of High Efficient Quasi-Single-Cycle 3 and 6THZ Pulses using Multilayer Structures OH1/SiO2 and DSTMS/SiO2
We propose that high efficient terahertz (THz) multilayer structures are composed of DSTMS/SiO2 and OH1/SiO2 at 3 and 6THz frequencies. We show that the efficiencies of these structures are higher than DAST/SiO2 structure in both of 3 and 6THz frequencies. OH1/SiO2 structure at 6THz has an efficiency as large as 10-1; at 3THz frequency, DSTMS/SiO2 structure has an efficiency as large as 10-...
