Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

open access: yesAdvanced Photonics Research
We investigate self‐sustained oscillations on microdrum resonators manufactured with molybdenum disulfide, under continuous‐wave laser excitation. Control over these oscillations is demonstrated building a simple radio‐over‐laser link.

Recent advances in underwater optical wireless communications

open access: yesUnderwater Technology: International Journal of the Society for Underwater, 2014
Abstract Optical wireless communications (OWC) are being consid-ered for use under water because sea water exhibits a win-dow of reduced absorption in the visible spectrum, particularly between 400–550nm. Recent technology has demonstrated the ability to support mid-range links (
