High-Performance Quantum Cascade Lasers: Optimized Design Through Waveguide and Thermal Modeling

S.S. Howard, Zhijun Liu, Daniel M. Wasserman, Angela Hoffman, Dae-sik Ko, C. F. Gmachl
IEEE Journal of Selected Topics in Quantum…
2007

We present a comprehensive model to study the thermal effects in quantum cascade (QC) lasers for continuous-wave (CW) operation at and above room temperature. This model self-consistently solves the… (More)

All-semiconductor plasmonic nanoantennas for infrared sensing.

Nano letters
2013

Infrared absorption spectroscopy of vibro-rotational molecular resonances provides a powerful method for investigation of a wide range of molecules and molecular compounds. However, the wavelength of… (More)

Room-temperature continuous-wave quantum cascade lasers grown by MOCVD without lateral regrowth

Zhijun Liu, Daniel M. Wasserman, +6 authors Fow-Sen Choa
IEEE Photonics Technology Letters
2006

We report on room-temperature continuous-wave (CW) operation of lambda~8.2 mum quantum cascade lasers grown by metal-organic chemical vapor deposition without lateral regrowth. The lasers have been… (More)

6 nm half-pitch lines and 0 . 04 μ m 2 static random access memory patterns by nanoimprint lithography

A key issue in nanoimprint lithography (NIL) is determining the ultimate pitch resolution achievable for various pattern shapes and their critical dimensional control. To this end, we demonstrated… (More)

Temperature dependent diffusion characterization of In(Ga)As/InAsSb type-II superlattice infrared detectors

Na Yeong Yoon, C. Reyner, G. Ariyawansa, John E. Scheihing, James C. Mabon, Daniel M. Wasserman
Conference on Lasers and Electro-Optics (CLEO)
2017

We present the temperature dependent minority carrier mobility of Ga-content varying InGaAs/InAsSb superlattice infrared detectors by combining time-resolved photoluminescence and electron beam… (More)

Optical Mapping of RF Field Profiles in Resonant Microwave Circuits

Sukrith Dev, Runyu Liu, Jeffery W. Allen, Monica S. Allen, B. Wenner, Daniel M. Wasserman
IEEE Photonics Technology Letters
2018

We demonstrate a technique for mapping the electric field profiles in resonant microwave circuits. Optical pumping of microwave circuits fabricated on semiconductor substrates is shown to result in a… (More)

Enhanced responsivity resonant RF photodetectors.

Ruipeng Liu, Sukrith Dev, +7 authors Daniel M. Wasserman
Optics express
2016

The responsivity of room-temperature, semiconductor-based photodetectors consisting of resonant RF circuits coupled to microstrip buslines is investigated. The dependence of the photodetector… (More)

Narrow stripe-width, low-ridge configuration for high power quantum cascade lasers

Anton Lyakh, Peter S. Zory, +5 authors D. J. H. Bour
Conference on Lasers and Electro-Optics (CLEO)
2007

Low-ridge-configuration, quantum-cascade lasers operating at 5.3 mum provide, at 80 K, 12 W peak-pulsed power at 14 A drive. A model of current spreading that takes into account the lateral variation… (More)

Mid-infrared designer metals

Stephanie A. Law, David C. Adams, Andrew M. Taylor, Daniel M. Wasserman
IEEE Photonics Conference
2012

We demonstrate the utility of epitaxially-grown, highly-doped semiconductors as plasmonic designer metals, with plasma wavelengths across a broad range of the mid-infrared. Micro-particles fabricated… (More)

Towards nano-scale photonics with microscale photons : the opportunities and challenges of mid-infrared plasmonics

Viktor Podolskiy, Daniel M. Wasserman
2013

Surface plasmon polaritons and their localized counterparts, surface plasmons, are widely used at visible and near-infrared (near-IR) frequencies to confine, enhance, and manipulate light on the… (More)
