On-chip, high-sensitivity temperature sensors based on dye-doped solid-state polymer microring lasers
We developed a chip-scale temperature sensor with a high sensitivity of 228.6 pm/°C based on a rhodamine 6G (R6G)-doped SU-8 whispering gallery mode microring laser. The optical mode was largely…

Monolithic optofluidic ring resonator lasers created by femtosecond laser nanofabrication.
TLDR
Detailed analysis shows that the Q-factor of the optofluidic ring resonator is 3.3 × 10(4), which is limited by both solvent absorption and scattering loss, suggesting the feasibility of using a femtosecond laser to create high quality optical cavities.

Dielectrically Transduced Single-Ended to Differential MEMS Filter
TLDR
This technology provides 1MHz channel select filtering while eliminating the need for RF switches and baluns in front-end transceivers and achieves 8dB insertion loss with -50dB stop-band rejection and -48dB common-mode suppression.
