Robust and flexible free-standing all-dielectric omnidirectional reflectors
A chalcogenide glass and a polyamideimide polymer are used to fabricate freestanding membranes (see figure). The membranes are less than 3 pm thick but provide a near-unity omnidirectional reflection band in the near infrared. Optomechanical tuning of the filter response and manual construction of microcavities are demonstrated.
