Mechanically Contacted Distributed-Feedback Optical Microcavity
Nanomaterials, 2022 We report a construction of distributed-feedback (DFB) optical microcavities, which is realized through mechanical contact between a high-quality planar thin film of a polymeric semiconductor and a large-area homogeneous nanograting. Using poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3] thiadiazol-4,8-diyl)] (F8BT) as the active medium for the ...

Optical receiver with optical feedback
Electronics Letters, 1987 A new optical receiver with optical feedback is described. The optical feedback is implemented by feeding back a fraction of the light from an optical source which is connected to the output of the receiver, to an extra photodiode. The proposed theoretical model was found to be in good agreement with measurement results on a 5 MHz optical receiver.
