Abstract:
We have been investigating the submillimeter/terahertz camera with the large format SIS (Superconductor - Insulator - Superconductor) photon detector array. To realize the submillimeter/terahertz camera, a cryogenic readout system matching to the SIS detector properties is necessary. For this readout system, we have developed several kind of ICs (Integrated Circuits) constructed with n-channel GaAs-JFETs. We also have designed and manufactured 32-channel multi-chip-modules with these ICs. These modules can make 32-channel parallel input photo current signals into one or two serial output voltage signal(s). Size of these is 40mm × 30mm × 2mm. The estimated total power dissipation is about 400 µW.
