Sub-mm results
from lumped-element UTCs of own design and production at University of Sheffield, using 2”-InGaAs-UTC-structured InP-wafers from SWI |
 Left: One of the micro-fabricated UTC-photodiodes
of 5mu diameter, integrated into a bow-tie antenna. | |
Right: Output spectrum of 5 mu diameter photodiode, tested
for submm-generation, 200mW dual laser pump power. The cut-off frequency is 200
GHz, this is ultra-fast. |
