Colloidal Quantum Dots and J-Aggregating Cyanine Dyes for Infrared Photodetection
Osedach, Timothy (2012-12-13)The emergence of nanostructured semiconducting materials enables new approaches toward the realization of photodetectors that operate in the technologically important near- and short-wave infrared (NIR and SWIR) spectral ... -
The Effect of Intracavity Field Variation on the Emission Properties of Quantum Cascade Lasers
Mansuripur, Tobias S. (2016-09-14)A common and powerful simplification in laser physics is to ignore the spatial dependence of the intracavity field intensity, and instead replace it with its average value. This approach can elucidate many aspects of laser ... -
Fourier optics for wavefront engineering and wavelength control of lasers
Blanchard, Romain (2014-02-25)Since their initial demonstration in 1994, quantum cascade lasers (QCLs) have become prominent sources of mid-infrared radiation. Over the years, a large scientific and engineering effort has led to a dramatic improvement ... -
Metasurface Diffraction Gratings for Arbitrary Polarization State Generation and Measurement
Zaidi, Muhammad Aun Abbas (2017-07-14)Metasurfaces, nano-structured arrays of phase-shifting elements, can sample phase functions at sub-wavelength scales. These novel devices hold the potential to replace bulky, conventional optics with ultra-thin devices ... -
Near-Field Optical Forces: Photonics, Plasmonics and the Casimir Effect
Woolf, David Nathaniel (2013-10-08)The coupling of macroscopic objects via the optical near-field can generate strong attractive and repulsive forces. Here, I explore the static and dynamic optomechanical interactions that take place in a geometry consisting ... -
Optics at interfaces: ultra-thin color coatings, perfect absorbers, and metasurfaces
Kats, Mikhail A (2014-02-25)The vast majority of optical components and devices in use today can be grouped under the umbrella of ``bulk optics''; i.e. they generally have a non-negligible thickness compared to the wavelength of light. This is true ...
