Abstract

We characterized the DC transport response of a diode embedded in a THz quantum cascade laser as the laser current was changed. The overall response is described by parallel contributions from the rectification of the laser field due to the non-linearity of the diode I–V and from thermally activated transport. Sudden jumps in the diode response when the laser changes from single mode to multi-mode operation, with no corresponding jumps in output power, suggest that the coupling between the diode and laser field depends on the spatial distribution of internal fields. The results demonstrate conclusively that the internal laser field couples directly to the integrated diode.

(a) Micrograph of the 170 μm wide by 3 mm long transceiver with diode embedded in QCL ridge waveguide. The measurement circuit for diode rectification and IF signals is shown with the dashed grey region indicating a bias tee. (b) Light output - current and voltage - current characteristic (L-I-V) at 20 K (blue), 30 K (green) and 40 K (orange). The diode I–V curves at all three temperatures are shown in the inset, but are virtually identical.

(a) The percent change in DC diode current as a function of QCL bias current at 20 K for diode bias voltages of −0.6 V (orange), −0.4 V (red), +0.4 V (blue) and +0.6 V (teal). (b) The DC diode response (black circles) at 20 K with 450 mA laser current is compared to the second derivative of the diode I–V (blue line), the temperature dependence of the diode I–V (red line), and a fit (green line) to the data as a function of diode voltage bias. The three solid colored curves correspond to the three terms in Eq. (3) as described in the text.

(a) The AC rectified diode response at 20 K as a function of QCL current modulation amplitude. The QCL current was modulated around 430 mA (black circles) and 580 mA (red diamonds). (b) The DC and AC diode responses at 20 K are compared at three different diode bias points, 0.60 V (black), 0.65 V (red), and 0.75 V (blue). Solid lines are the AC change in diode current. Diamonds are the calculated derivative of the DC change in diode current.
