Silicon-integrated Single Pixel Terahertz Camera

Abstract

We present an all-electronic THz single pixel camera (SPC) implemented in a commercial 0.13 μm SiGe BiCMOS technology. The key enabling element is a source array system-on-a-chip (SoC) consisting of 8 × 8 unlocked source pixels. Together, they radiate maximum 10.8 mW of power at 0.42 THz. The SoC includes programmable logic to project structured, reconfigurable THz light that can be multiplexed in space and modulation frequency. It is paired with a single pixel direct power detector to demonstrate an SPC system that can potentially capture high dynamic range THz images at thousands of frames each second.
