Nano-antennas are replicas of antennas that operate at radio-frequencies, but with considerably smaller dimensions when compared with their radio frequency counterparts. Noble metals based nano-antennas have the ability to enhance photoinduced phenom

In this paper, we analyze the performance of two tantalum-based boride (TaB and TaB2) microparticles as potential saturable absorbers for high-power fiber lasers. Both materials are ultrahigh temperature ceramics with melting points above 3000 °C, b

Ultra-high temperature ceramics are widely used in hypersonic vehicles, nuclear reactors, and in other equipment that operates under extreme conditions. In particular, Zirconium Boride (ZrB12) is an ultra-high temperature refractory ceramic material

Nano-antennas on silica or semiconductor substrate cannot handle high power due to their low thermal conductivity. This paper shows that high thermal conductivity substrates such as diamond can handle 20 times higher fluence than silica substrate bas

In this paper, we experimentally study broadband perfect absorber based upon tungsten boride. We show that the absorptance of the WB perfect absorber has much better temperature stability when compared with an Al based absorber: its absorptance chang

As organic-based electro-optic (EO) modulators continually improve toward meeting the high performance required by new and developing photonic technologies, the challenge of compact and low loss packaging needs to be addressed.Because organic-based E

Nano-antennas cannot handle high energy density (fluences) due to their small footprint. In this paper, we propose chromium based nano-antenna and experimentally show that it can handle 110 times higher fluence than gold (Au) counterpart without a si

In general, noble metals based nano-antennas cannot work at high power applications such as heat resisted magnetic recording, solar thermo-photovoltaics, and nano-scale heat transfer systems. These antennas are prone to being damaged at sufficiently

This article presents a microstrip ring resonator technique for characterizing thin film substrates up to 110 GHz. A coupling structure was designed to efficiently couple energy into rings despite the tight microstrip-substrate confinement. Various r
