Abstract:
1. An optoelectronic switch transmitter using millimeter wavelength (MMW), comprising an input device, said input device comprising a pulse pattern generator (PPG); a device under test (DUT), said DUT comprising an antenna-signal processor, said antenna-signal processor comprising an error detector (ED), wherein said SMF has a probe at a first end to be optically coupled with wherein said lensed fiber is positioned at a side of said SMF and is connected with a second end of said SMF; wherein said input device receives a collimated beam of optical signals and focuses said collimated beam to move said optical signals from said SMF into said DUT through said lensed fiber; wherein said PPG generates 12.5 Gbit/s pulse signals entering into said DUT; wherein said DUT is positioned in a waveguide to be combined to a first horn antenna through said waveguide; wherein said optoelectronic switch has a structure of p-n-p-i-n epi-layers, comprising, from top to bottom, wherein said epi-layers are grown on a semiconductor substrate selected from a group consisting of a thoroughly-doped semiconductor substrate and a semi-insulating semiconductor substrate; wherein said DUT integrates said pulse signals and said optical signals into MMW signals having IFs and sends said MMW signals having IFs to said first horn antenna to emit said MMW signals having IFs; wherein said antenna-signal processor is connected with a second horn antenna to receive and magnify W-band of said MMW signals, and then said MMW signals having said W-band magnified (W-band MMW signals) are processed through power check to obtain voltage level signals, and then IF voltages of said W-band MMW signals are magnified based on said voltage level signals; wherein said ED is electrically connected with said antenna-signal processor to receive said W-band MMW signals and obtain an error rate in said W-band MMW signals; wherein a voltage pulse is applied to a device under test (DUT) for switching the photo-generated MMW power, the DUT is operated under reverse bias; wherein an optical light source with modulated MMW envelop is injected on to DUT for MMW power generation.
