SCIENTIFIC HIGHLIGHTS
Quantum Cascade Lasers (QCLs) and Bandstructure Enginrering.
These lasers, represent the most important highlight of the research of Capasso and his team over a 20 year period on band-structure engineering, a technique to design and implement artificially structured ( “man-made”) semiconductor ,materials and related phenomena/ devices, of which he is the pioneer and which revolutionized the design of heterojunction devices. Invented and demonstrated by Capasso and his group in 1994,
QCLs are the first lasers in which the emission wavelength can be tailored over an extreme broad range using quantum design. They have revolutionized mid-infrared photonics, as they represent the first high performance and reliable semiconductor lasers for this technologically and scientifically important spectral region. They are finding widespread use in scientific and industrial applications: high-resolution spectroscopy, chemical sensing and trace gas analysis, atmospheric chemistry, combustion and medical diagnostics. Numerous companies are commericializing QC lasers and related sensors .
A tutorial account of Capasso's research on quantum cascade lasers has appeared in a book for a lay audience on materials research by Ivan Amato ("Stuff: the materials the world is made of", Basic Books, New York, NY, 1997) and in the article "Diminishing dimensions" in a special issue of Scientific American, entitled the Solid-State Century,
1997-1998.
2. Quantum phenomena in nanostructures and novel heterostrcuture /quantum devices
 Observation of electronic bound-states in the continuum above a potential well, verifying a 1929 prediction by Von Neumann and Wigner.
 Coupled quantum well semiconductors with giant intersubband nonlinear optical susceptibilities, probably the highest ever observed. These nonlinearities have been
3

successfully used by Capasso and his group within the active region of QC lasers to further enhance their wavelength agility and functionality.
 Demonstration of tunable band discontinuities with doping interface dipoles. This method has for the first time made it possible to tailor a fundamental property of heterojunctions.
 Observation of resistance resonance associated with quantum interference in coupled quantum wells.
 Tunable Fano interference in potential wells.
 Observation of sequential resonant tunneling through a quantum well superlattice.
 Observation of giant photoconductive gain by effective mass filtering.
 Invention of solid-state photomultipliers.
 Invention and demonstration of resonant tunneling bipolar transistors and circuits with reduced complexity. This work has stimulated new research in multiple valued logic and multilevel coding.

Physics of deformed laser resonators
 Bow-tie lasers based on chaotic resonators;
 Kolmogorov-Arnold-Moser transition to chaos in deformed semiconductor lasers
 Whispering gallery mode lasers with highly directional emission: elliptical notched resonators and Limaçon resonators
4.
Plasmonics and Metasurfaces.
 Generalized laws of reflection and refraction demonstrated and theoretical derived for a general class of designer metasurfaces.
 Flat optics based on metasurfaces such as aberration free flat lenses, vortex plates, background free quarter wave plates
 New surface plasmon coupling coupler (fishbone grating), allowing for the first time polarization controlled directional coupling.
 Plasmonic laser antennas with ultrahigh intensity nanoscale spots in the near-field
 Wavefront engineering of light sources including highly collimated mid-ir and fra-ir semiconductor lasers; multibeam collimated lasers, etc.
 Core-shell nanoparticles clusters (trimers, quadrumers and heptamers) exhibiting magnetic activity in the near infrared and giant Fano resonances.

Casimir forces
This research has focused on basic studies of the Casimir effect, i.e. the attractive force between uncharged metals and dielectrics due to vacuum fluctuations, using
MicroElectroMechanicalSystems (MEMS) and atomic force techniques and of the repulsive Casmir force. This line of research is ultimately aimed at engineering these quantum electrodynamical forces by designing quantum fluctuations through controlled changes (shapes and materials) of the boundary conditions of the electromagnetic fields.
Highights of this work are:
 First measurement of the repulsive Casimir-Lifshitz force .
 Demonstration of actuators and nonlinear oscillators using the Casimir force, the observation of the effect of the skin depth on the Casimir force;
 Observation of the Casimir effect in a fluid
