摘要: Using point‐contact metal‐insulator‐metal diodes, we have demonstrated heterodyne detection of visible laser radiation at frequency differences up to 2.5 THz (generated by a 119‐μm laser). The signal noise on the observed rf beat falls off 2.3 dB/octave difference and would seem indicate that 30‐THz beats will be obervable with improved stability or averaging. While diode detector ‘‘bandwidth’’ per se has not been evaluated, these measurements demonstrate an increase in which can measured more than order magnitude over previously reported.
