typical sensitivity is 600mV/mW in 0.11~0.17THz

and tangential signal sensitivity (TSS) is superior than -29dBm.To the 0.15THz frequency doubler

highest measured multiply efficiency is 7.5%

and typical efficiency is 6.0% in 0.1474~0.152THz.To the 0.18THz frequency doubler

highest measured multiply efficiency is 14.8%

and typical efficiency is 8.0% in 0.15~0.2THz.To the 0.15THz SHM

lowest measured conversion loss is 10.7dB

and typical conversion loss is 12.5dB in 0.135~0.165THz.To the 0.18THz SHM

lowest measured conversion loss is 5.8dB

and typical conversion loss is 13.5dB and 11.5dB in 0.165~0.2THz and 0.21~0.24THz

respectively.
