Cavity-Enhanced Vernier Spectroscopy with a Chip-Scale Mid-Infrared Frequency Comb
Lukasz A. Sterczewski, Tzu-Ling Chen, Douglas C. Ober +7
Chip-scale optical frequency combs can provide broadband spectroscopy for diagnosing complex organic molecules. They are also promising as miniaturized laser spectrometers in appli…
Battery-operated mid-infrared diode laser frequency combs
Lukasz A. Sterczewski, Mathieu Fradet, Clifford Frez +2
Mid-wave infrared (MIR, 3--5 m) optical frequency combs (OFC) are of critical importance for spectroscopy of fundamental molecular absorption features in space and terrestrial a…
Mid-infrared dual-comb spectroscopy with low drive-power on-chip sources
Lukasz A. Sterczewski, Jonas Westberg, Mahmood Bagheri +9
Two semiconductor optical frequency combs consuming less than 1 W of electrical power are used to demonstrate high-sensitivity mid-infrared dual-comb spectroscopy in the important…
Efficient Dielectric Metasurface Collimating Lenses for Mid-Infrared Quantum Cascade Lasers
Amir Arbabi, Ryan M. Briggs, Yu Horie +2
Light emitted from single-mode semiconductor lasers generally has large divergence angles, and high numerical aperture lenses are required for beam collimation. Visible and near in…
Dielectric Metasurfaces for Complete Control of Phase and Polarization with Subwavelength Spatial Resolution and High Transmission
Amir Arbabi, Yu Horie, Mahmood Bagheri +1
Metasurfaces are planar structures that locally modify the polarization, phase, and amplitude of light in reflection or transmission, thus enabling lithographically patterned flat…
Subwavelength-thick Lenses with High Numerical Apertures and Large Efficiency Based on High Contrast Transmitarrays
Amir Arbabi, Yu Horie, Alexander J. Ball +2
We report subwavelength-thick, polarization insensitive micro-lenses operating at telecom wavelength with focal spots as small as 0.57 wavelengths and measured focusing efficiency…
Photonic Cavity Synchronization of Nanomechanical Oscillators
Mahmood Bagheri, Menno Poot, Linran Fan +2
Synchronization in oscillatory systems is a frequent natural phenomenon and is becoming an important concept in modern physics. Nanomechanical resonators are ideal systems for stud…
Backaction limits on self-sustained optomechanical oscillations
M. Poot, K. Y. Fong, M. Bagheri +2
The maximum amplitude of mechanical oscillators coupled to optical cavities are studied both analytically and numerically. The optical backaction on the resonator enables self-sust…
Dynamic manipulation of mechanical resonators in the high amplitude regime through optical backaction
Mahmood Bagheri, Menno Poot, Mo Li +2
Cavity optomechanics enables active manipulation of mechanical resonators through backaction cooling and amplification. This ability to control mechanical motion with retarded opti…
