Stability of heterodyne terahertz receivers
In this paper we discuss the stability of heterodyne terahertz receivers based on small volume NbN phonon cooled hot electron bolometers HEBs . The stability of these receivers can be broken down in two parts: the intrinsic stability of the HEB mixer and the stability of the local oscillator LO signal injection scheme. Measurements show that the HEB mixer stability is limited by gain fluctuatio...
متن کاملTHz QCLs for heterodyne receivers and wavelength modulation spectroscopy
Milliwatt average power terahertz quantum cascade lasers (THz-QCLs, 2 THz to 5 THz) have been developed for spectroscopy and as local oscillators for heterodyne receivers. Novel DFB THz-QCLs have been fabricated and show single-mode operation. The narrow line widths of <10 MHz and stark shift tuning of of 6 GHz, allows for wavelength modulation spectroscopy of low pressure gasses in the unexplo...
متن کاملAnalysis of Optimum Heterodyne Receivers for Coherent Lidar Applications
A full analysis of the combined effects of all the noise sources of optical heterodyne receiver and the interaction between the competing control parameters of the receiver detector and pre-amplifier will be presented. This analysis provides the mean for true optimization of the coherent lidar receiver. The significance of the optimization of heterodyne receiver is shown for 2-micron coherent l...
متن کاملCoherent Heterodyne OCDMA with Sourceless and Colorless Receivers
We present a new, coherent, heterodyne OCDMA scheme that conveys the signal and reference to each user in a multiple access network via one fiber. The receiver is sourceless and colorless. Bit error rate performance is characterized as a function of system parameters under various conditions.
متن کاملThe design and sensitivity of microwave frequency optical heterodyne receivers
Recent advances in high speed photodetector and microwave receiver technology make microwave frequency optical heterodyning an attractive approach for the detection of a number of coherent Raman and Brillouin scattering experiments. We have therefore analyzed the sensitivity of microwave frequency optical heterodyne receivers. Experimental tests on a visible wavelength receiver operating at 13....
