Single-mode lasing from top-down fabricated gallium nitride nanowires

IEEE Photonic Society 24th Annual Meeting, PHO 2011

Wright, J.B.; Li, Q.M.; Luk, Ting S.; Brener, Igal B.; Wang, George T.; Westlake, K.R.; Lester, L.F.

We study lasing in individual top-down fabricated GaN nanowires by optical pumping. We observe single mode emission with a side mode suppression of 15 dB, linewidths of less than 1 nm and thresholds as low as 250 kW/cm 2. © 2011 IEEE.

Interactions in 2D and 3D mid-infrared metamaterials

2011 5th Rio De La Plata Workshop on Laser Dynamics and Nonlinear Photonics, LDNP 2011

Brener, Igal B.

We explore the issue of interactions between metamaterial resonators and different types of absorbers placed in proximity to these resonators. Very clear anticrossing behaviour and level splitting is observed when IR phonons interact with planar metamaterials. More complex dipole transitions can be designed using semiconductor bandgap engineering. We show experimentally the coupling between metamaterial resonances and intersubband transitions and discuss this mechanism for electrical tuning of metamaterials throughout the optical infrared spectral region. Finally we will discuss interactions in 3D dielectric resonator metamaterials. © 2011 IEEE.

Multilayer infrared metamaterial fabrication using membrane projection lithography

Journal of Vacuum Science and Technology. B, Nanotechnology and Microelectronics

Wendt, J.R.; Brener, Igal B.; Sinclair, Michael B.

Membrane projection lithography is extended from a single layer fabrication technique to a multilayer process, adding polymeric backfill and planarization after each layer is completed. Unaligned contact lithography is used as a rapid prototyping tool to aid in process development, patterning resist membranes in seconds without requiring long e-beam write times. The fabricated multilayer structures show good resistance to solvent attack from subsequent process steps and demonstrate in-plane and out of plane multilayer metallic inclusions in a dielectric host, which is a critical step in the path to develop bulklike metamaterials at optical frequencies.
