[2H12] Development of an Iridium-gold bilayer optical transition edge sensor
Keywords:Transition Edge Sensor, infrared single photon, photon number resolving detector, cryogenic, Micro fabrication
We have developed transition edge microcalorimeter with an energy resolution of 0.65eV fullwidth
at half-maximum for the pulse laser about 850nm.
Due to realize Quantum key distribution and quantum computer, it is necessary to measure photons in the mid-infrared.
For that reason, We achieved this high energy resolution by using Au-Ir bilayer and the
process of device.
As a result of an experiment using Au-Ir bilayer, the point of superconducting transition
temperature became about 175mK. In addition to this, we can control the superconducting
transition temperature by changing the ratio of bilayer.
We also used sleeve in order to improve the accuracy of alignment with pulse laser and
transition edge sensor.
