| Popis: |
An optical reflective cavity in vertical extrinsic SiC photoconductive switches is developed to improve the light absorption or photoelectric responsivity with the fiber triggering. The optical reflective cavity consists of a total reflector, a center reflector, and a fiber to form a quasi-total internal light trap. The fiber with a core diameter of $400 ~\mu \text{m}$ is inserted into a hole reflector. Both simulations and experiments reveal that the light absorption of the device has been improved significantly. Compared with traditional vertical devices without optical configuration, the device demonstrates a $2.29\times $ improvement in photoelectric responsivity. Using the optical reflective cavity, the SiC photoconductive switch achieves a power capacity of 3.1 MW with a peak photocurrent of 141 A at a laser energy of 15 mJ. |
