Coherent combining of two quantum-cascade
lasers in a Michelson cavity, Guillaume Bloom 1 ,
Christian Larat 1 , Eric Lallier 1 , Mathieu Carras 2 ,
Xavier Marcadet 2 ; 1 Thales Research and Technology,
France; 2 Alcatel Thales III-V Lab, France.
A Michelson type cavity has been developed to
achieve coherent combining of two quantumcascade
lasers emitting at 4.5 µm. We report a cw
combining efficiency of 85% with a good beam
quality (M 2 < 1.4).
ATuA1 • 08:00 Tutorial
Upcoming NASA Earth Science Decadal Missions:
ICESat II and DESDynI, Matthew McGill 1 ,
Thorsten Markus 1 ; 1 NASA Goddard Space Flight
Center, USA. This presentation will summarize
the motivation for space-based laser altimetry, the
science requirements for ICESat-2, and the current
concept for the ICESat-2 mission. ICESat-2 will
employ a photon-counting measurement approach
using a high-repetition rate laser in a multi-beam
configuration.

Diffractive coupling engineered sharp LC
resonance in terahertz metamaterials, Ranjan
Singh 1,2 , Carsten Rockstuhl 3 , Weili Zhang 1 ; 1 School
of Electrical and Computer Engineering, Oklahoma
State Univ., USA; 2 CINT, Los Alamos National
Lab, USA; 3 Inst. of Condensed Matter Theory and
Solid State Optics, Friedrich-Schiller-Universität
Jena, Germany. We show that the fundamental
LC resonance has its highest quality factor for
a period matching the resonance wavelength in
the substrate material. This occurs due to the
simultaneous excitation of the lowest order diffraction
mode.

Optical Parametric Generation of Mid-Infrared
Picosecond Pulses Beyond 6 microns in CdSiP 2 ,
Olivier Chalus 1 , Adolfo Esteban-Martin 1 , Peter G.
Schunemann 2 , Kevin T. Zawilski 2 , Jens Biegert 1,3 ,
Majid Ebrahim-Zadeh 1,3 ; 1 Nonlinear Optics, ICFO-
Institut de Ciencies Fotoniques, USA; 2 BAE Systems,
USA; 3 Institucio Catalana de Recerca i Estudis
Avancats (ICREA), Spain. We report parametric
generation of near- and mid-infrared picosecond
pulses at 100 kHz in CdSiP 2 pumped at 1.064 microns,
providing 154 mW of idler at 6.204 microns
and 1.16 W of signal at 1.282 microns.

Temperature Dependence of the Transparency
Current Density in Mid-Infrared Quantum
Cascade Lasers, Yamac Dikmelik 1 , Jacob B.
Khurgin 1 , Matthew Escarra 2 , Peter Q. Liu 2 , Claire
F. Gmachl 2 ; 1 Electrical and Computer Engineering,
Johns Hopkins Univ., USA; 2 Electrical Engineering,
Princeton Univ., USA. We analyze the temperature
dependence of the transparency current density in
mid-infrared quantum cascade lasers and assess
its contribution to measured threshold current
density for a laser with low voltage defect.
CTuC3 • 08:30
Single-Mode Interband Cascade Lasers with
Coupled Ring Resonators, Jerry R. Meyer 1 ,
William W. Bewley 1 , Chadwick L. Canedy 1 , Chul
Soo Kim 1 , Mijin Kim 1 , James R. Lindle 1 , Joshua
Abell 1 , Igor Vurgaftman 1 ; 1 Naval Research Lab,
USA. We report Fabry-Perot interband cascade
lasers coupled to rectangular ring resonators
that produce up to 5 mW of cw power in a single
spectral mode at 3 C. The tuning range at 3-28 C
exceeds 8 nm.
Dr. Matthew McGill is a research scientist at
NASA’s Goddard Space Flight Center. Dr. McGill
has developed multiple laser remote sensing
instruments, primarily for use on high-altitude
research aircraft. He is currently serving as Instrument
Scientist for the ICESat-2 mission, where his
role is to ensure that the science requirements for
the mission are met by the instrument implementation
being developed. As part of that role, Dr.
McGill has also been responsible for developing an
airborne demonstrator instrument to validate the
proposed ICESat-2 measurement concept.

Temperature tunable behavior of planar
terahertz metamaterials fabricated on bulk
strontium titanate substrates, Ranjan Singh 1 , Antoinette
J. Taylor 1 , Hou-Tong Chen 1 ; 1 CINT, Los Alamos
National Lab, USA. We demonstrate thermal
tuning of the inductive capacitive (LC) resonance
in terahertz metamaterials made up of gold splitring
resonator (SRR) arrays on ferroelectric bulk
Strontium Titanate (STO) substrates.

Time- and Frequency-Domain Imaging of
Dynamics in Terahertz Meta-Atoms, Kazunori
Serita 2 , Juraj Darmo 1,2 , Daniel Dietze 1 , Iwao
Kawayama 2 , Hironaru Murakami 2 , Karl Unterrainer
1 , Masayoshi Tonouchi 2 ; 1 Photonics Inst.,
Vienna Univ. of Technology, Austria; 2 Inst. of Laser
Technology, Osaka Univ., Japan. Visualization
of the dynamics of the electromagnetic resonators
used to build metamaterial is presented.
Observed data provides detailed information on
the interaction between free space radiation and
the resonator.

Picosecond mid-IR optical parametric amplifier
based on GaS 0.4 Se 0.6 pumped by a Nd:YAG
laser system at 1064 nm, Kentaro Miyata 1 , Georgi
Marchev 1 , Aleksey Tyazhev 1 , Vladimir Panyutin 1 ,
Valentin Petrov 1 ; 1 Max-Born-Inst., Germany. Operation
of a GaS 0.4 Se 0.6 optical parametric amplifier
is demonstrated in the 5-11 µm tuning range with
maximum energies ~10 µJ for sub-30-ps pulse
durations and performance ~3 times better than
with pure GaSe.

Parametric Amplifiers, Gideon Alon 1 , Oo-Kaw
Lim 1 , Amar Bhagwat 1 , Chao-Hsiang Chen 1 , Michael
Vasilyev 2 , Prem Kumar 1 ; 1 Electrical Engineering
and Computer Science, Northwestern Univ., USA;

Electrical Engineering, Univ. of Texas at Arlington,
USA. We demonstrate a two-stage system of
cascaded traveling-wave phase-sensitive optical
parametric amplifiers, achieving 10 dB secondstage
amplification (5 dB deamplification) on top
of the amplification (deamplification) provided
by the first stage.
