Analyzing Custom Proof Masses and Quantum Limits of a Manufacturable Cavity Optical Levitation Solution
This report details results of a one-year LDRD to understand the dynamics, figures of merit, and fabrication possibilities for levitating a micro-scale, disk-shaped dielectric in an optical field. Important metrics are the stability, positional uncertainty, and required optical power to maintain levitation. Much of the results are contained in a publication written by our academic alliance collaborators. Initial structures were grown at Sandia labs and a test fabrication flow was executed. Owing to our strength in VCSEL lasers, we were particularly interested in calculations and fabrication flows that could be compatible with a VCSEL light source.
Compact, Pull-in-Free Electrostatic MEMS Actuated Tunable Ring Resonator for Optical Multiplexing
Optics InfoBase Conference Papers
We present an optical wavelength division multiplexer enabled by a ring resonator tuned by MEMS electrostatic actuation. Analytical analysis, simulation and fabrication are discussed leading to results showing controlled tuning greater than one FSR.

Thermal and Loss Characterization of Mechanically Released Whispering Gallery Mode Waveguide Resonators
Optics InfoBase Conference Papers
We present an empirical methodology for thermally characterizing and determining absorption and scattering losses in released ring whisper gallery mode optical resonators. We used the methodology to deduce absorption and scattering contributions in Q = 308,000 silicon nitride resonators coupled to on-chip waveguides.

All-Semiconductor Coupled-Cavity VCSELs for Narrow Linewidth
Conference Digest - IEEE International Semiconductor Laser Conference
We demonstrate an all-semiconductor coupled-cavity VCSEL designed to achieve narrow linewidth at 850 nm. A resonant AlGaAs cavity of thickness 1,937 nm (8 wavelengths) is situated below the 3-quantum-well active region and results in an effective coupled-cavity length of 36 wavelengths.

Mode selection and tuning of single-frequency short-cavity VECSELs
Proceedings of SPIE - The International Society for Optical Engineering
We report on mode selection and tuning properties of vertical-external-cavity surface-emitting lasers (VECSELs) containing coupled semiconductor and external cavities of total length less than 1 mm. Our goal is to create narrowlinewidth (<1MHz) single-frequency VECSELs that operate near 850 nm on a single longitudinal cavity resonance and tune versus temperature without mode hops. We have designed, fabricated, and measured VECSELs with external-cavity lengths ranging from 25 to 800 μm. We compare simulated and measured coupled-cavity mode frequencies and discuss criteria for single mode selection.
