Analyzing Custom Proof Masses and Quantum Limits of a Manufacturable Cavity Optical Levitation Solution

Grine, Alejandro J.; Serkland, Darwin K.; Schultz, Justin S.; Wood, Michael G.; Finnegan, Patrick S.; Weatherred, Scott E.; Peake, Gregory M.; Sandoval, Annette S.; Alliman, Darrel A.; Li, Tongcang L.; Seberson, Troy S.

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.

All-Semiconductor Coupled-Cavity VCSELs for Narrow Linewidth

Conference Digest - IEEE International Semiconductor Laser Conference

Serkland, Darwin K.; Morin, Theodore J.; Grine, Alejandro J.; Peake, Gregory M.; Kendall, Wesley Y.; Wood, Michael G.; Hains, Christopher H.; So, Haley M.; Soudachanh, Amy L.; Geib, Kent M.

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.

Waveform optimization for resonantly driven MEMS switches electrostatically biased near pull-in

Proceedings of the IEEE International Conference on Micro Electro Mechanical Systems (MEMS)

Siddiqui, Aleem M.; Nordquist, Christopher N.; Grine, Alejandro J.; Lepkowski, Stefan M.; Henry, M.D.; Eichenfield, Matthew S.; Griffin, Benjamin G.

Biasing a MEMS switch close to static-pull in reduces the modulation amplitude necessary to achieve resonant pull-in, but results in a highly nonlinear system. In this work, we present a new methodology that captures the essential dynamics and provides a prescription for achieving the optimal drive waveform which reduces the amplitude requirements of the modulation source. These findings are validated both experimentally and through numerical modeling.

Mode selection and tuning of single-frequency short-cavity VECSELs

Proceedings of SPIE - The International Society for Optical Engineering

Serkland, Darwin K.; So, Haley M.; Peake, Gregory M.; Wood, Michael G.; Grine, Alejandro J.; Hains, Christopher H.; Geib, Kent M.; Keeler, Gordon A.

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.

Optomechanical spring effect readout in resonant micro-optical Sagnac gyroscopes design and scaling analysis

International Conference on Optical MEMS and Nanophotonics

Grine, Alejandro J.; Siddiqui, A.; Keeler, Gordon A.; Shaw, M.J.; Eichenfield, Matthew S.; Friedmann, Thomas A.; Douglas, Erica A.; Wood, M.G.; Dagel, D.J.; Hains, C.; Koch, L.F.; Nordquist, C.D.; Serkland, Darwin K.

We propose and theoretically analyze a new cavity optomechanical oscillator gyroscope. Mechanical frequency acts as a sensitive readout of rotation through the optomechanical spring and Sagnac effects. Remarkably, reducing device size improves scale factor.

Inductive coupling for increased bandwidth of aluminum nitride contour-mode microresonator filters

IEEE MTT-S International Microwave Symposium Digest

Nordquist, Christopher N.; Henry, M.D.; Nguyen, Janet H.; Clews, Peggy; Lepkowski, Stefan M.; Grine, Alejandro J.; Dyck, Christopher D.; Olsson, Roy H.

Inductive coupling and matching networks are used to increase the bandwidth of filters realized with aluminum nitride contour-mode resonators. Filter bandwidth has been doubled using a wirebonded combination of a wafer-level-packaged resonator chip and a high-Q integrated inductor chip. The three-pole filters have a center frequency near 500 MHz, an area of 9 mm × 9 mm, insertion loss of < 5 dB for a bandwidth of 0.4%, and a resonator unloaded Q of 1600.
