Ultra-sensitive Room-temperature Mid-infrared Detector using Phononic Crystal Oscillator
Abstract
We demonstrate a mid-infrared detector using a phononic crystal resonator fabricated on 128° Y-cut bulk lithium niobate substrate, featuring an absorbed noise equivalent power of 30 pW√ Hz and a response time constant of 0.3 ms.
