(1000 nm … 800 nm)x denotes the type of mounting as follows:
x = 0 unmounted chip 2 mm x 2 mm with 4 bond contact pads
x = h mounted on an Al disc with 25.4 mm φ and hyperhemispherical silicon substrate lens, 1m coaxial cable with BNC or SMA connector
x = a mounted on an Al disc with 25.4 mm φ and aspheric focusing silicon substrate lens, 1m coaxial cable with BNC or SMA connector
x = c mounted on an Al disc with 25.4 mm φ and aspheric collimating silicon substrate lens CL-12 for 12 mm THz beam diameter, 1m coaxial cable with BNC or SMA connector
x = h-f fiber coupled antenna with hyperhemispherical silicon substrate lens
x = l with aspheric focusing optical lens for free space laser excitation
x = p with preamplifier for detector antenna
