We demonstrate a new type of infrared plasmonic antenna for long-wavelength nano-scale enhanced sensing. The plasmonic materials utilized are epitaxially-grown semiconductor engineered metals, which results in high-quality, low-loss infrared plasmonic metals with tunable optical properties.
We demonstrate a mid-infrared perfect absorber fabricated only from highly-doped semiconductors. A strong (>98%) absorption resonance is observed which is effectively independent of lateral geometry, but highly dependent on the vertical profile.
The small size, light weight and low cost are main advantages of analog fiber links over coax links. In particular, analog fiber link is examined for photonic antenna (see Fig. 1) operating at high center frequencies in which a high power photodiode is deployed close to the antenna for downlink broadcasting [1]. High power and high output third order intercept point (OIP3) are among critical photodiode...
Voltage-dependent responsivity nonlinearities are characterized experimentally and analytically for uni-traveling carrier directional coupled photodiodes (DCPD) with two types of design variations. OIP3 data follows the voltage-dependent responsivity predictions for both MMI width and PD width variations of the baseline DCPD. A maximum OIP3 of 39dBm was achieved for a device with a 3μm wide PD at...
We demonstrate an efficient nanoscale electrical detector for propagating surface plasmons, tightly confined to nanoscale silver wires. Our technique is based on the near-field coupling between guided plasmons and a nanowire field-effect transistor. We demonstrate that this near-field circuit can efficiently detect the plasmon emission from a single quantum dot that is directly coupled to the plasmonic...
