Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, ...
Single junction type (a) and the proposed double junction type (b) solar cells are compared with the conventional TANDEM type (c) and the proposed face-to-face type (d) multi-junction connections. A ...
Fig. 1. (a) Epitaxy and mesa structure of the proposed MUTC-PD. (b) Simulated RF power versus photocurrent. (c) Electric field distributions in the depletion region at different photocurrents. (d) SEM ...
