Application of micro-pattern gaseous detectors (MPGD) to photon detection has been widely investigated over the past decades. A double micro-mesh gaseous structure (DMM) prototype is developed with a thermal bonding technique for this application. Excellent performance for detecting single photon has been demonstrated in various tests with X-ray and ultra-violet (UV) laser light. The gain of the DMM prototype can reach up to >106 for single electrons while maintaining a very low ion-backflow (IBF) ratio down to
