In general, to fit various application scenarios, different types of optical filters are needed and designed individually, which leads to high cost and long development times. Here we proposed a re…
Most existing hashing methods resort to binary codes for large scale similarity search, owing to the high efficiency of computation and storage. However, binary codes lack enough capability in simi…
Microcavity-feedback fiber-loop laser gives a promise for single-mode and tunable lasing. Here, a whispering gallery mode(WGM) microcavity-feedback fiber-loop laser is constructed and dynamic lasin…
