Adjustable SQUID-resonator direct coupling in microwave SQUID multiplexer for TES microcalorimeter array
We have succeeded in the first demonstration of a simple and accurate resonator-superconducting quantum interference device (SQUID) coupling for microwave SQUID multiplexers. A simple theory shows our direct coupling with adjustable fractional inductance in the SQUID loop can decrease the deviation of resonance frequencies from designed values in contrast to a conventional inductive coupling. O...
متن کاملModulated microwave surface impedance of superconducting films
We present details of an experimental method to measure the field modulated surface resistance (dR,/dH) of superconducting films accurately, which enables both field and temperature sweep experiments and is particularly useful for low-field or near T, measurements. The complex surface impedance Z,(H,T) =R,(H,T) + iX,(H, T) can also be simultaneously measured. This technique utilizes specially b...
متن کاملOptical time division multiplexer on silicon chip.
In this work, we experimentally demonstrate a novel broadband optical time division multiplexer (OTDM) on a silicon chip. The fabricated devices generate 20 Gb/s and 40 Gb/s signals starting from a 5 Gb/s input signal. The proposed design has a small footprint of 1mm x 1mm. The system is inherently broadband with a bandwidth of over 100nm making it suitable for high-speed optical networks on chip.
متن کاملSingle SQUID Multiplexer for Arrays of Voltage-biased Superconducting Bolometers
We describe a frequency domain superconducting quantum interference device (SQUID) multiplexer which monitors a row of low-temperature sensors simultaneously with a single SQUID. Each sensor is ac biased with a unique frequency and all the sensor currents are added in a superconducting summing loop. A single SQUID measures the current in the summing loop, and the individual signals are lock-in ...
متن کاملLongitudinal Impedance of the Squid Giant Axon
Longitudinal alternating current impedance measurements have been made on the squid giant axon over the frequency range from 30 cycles per second to 200 kc. per second. Large sea water electrodes were used and the inter-electrode length was immersed in oil. The impedance at high frequency was approximately as predicted theoretically on the basis of the poorly conducting dielectric characteristi...
