Peer effect of environmental information disclosure behavior in China:Empirical test based on "Real green" and "Fake green".

The quality of corporate environmental information disclosure is concerned by all sectors of society. Using data on Chinese listed A-share companies in heavy polluting industries from 2015 to 2022, this study examines whether the "quantity" and "quality" dimensions of corporate environmental information disclosure have peer effects in the same region. Further, it compares the mechanism and economic consequences of the "real green" and "fake green" behaviors.

Ringing phenomenon based measurement of weak mode-coupling strength in an optical microresonator.

There is always a coupling between the degenerate clockwise (CW) and counter-clockwise (CCW) modes in a whisperinggallery- mode (WGM) optical microresonator, since the surface of the microresonator can not be perfectly smooth. It is important to measure this coupling strength in many applications. When the coupling strength is strong, the conventional method by observing mode splitting in the stationary spectrum can be used to measure its value.

Ringing phenomenon based whispering-gallery-mode sensing.

Highly sensitive sensing is one of the most important applications of whispering-gallery-mode (WGM) microresonators, which is usually accomplished through a tunable continuous-wave laser sweeping over a whispering-gallery mode with the help of a fiber taper in a relative slow speed. It is known that if a tunable continuous-wave laser sweeps over a high quality whispering-gallery mode in a fast speed, a ringing phenomenon will be observed. The ringing phenomenon in WGM microresonators is mainly used to measure the Q factors and mode-coupling strengths.

Transmission spectra of sausage-like microresonators.

We experimentally develop a sausage-like microresonator (SLM) by making two microtapers on a single-mode fiber, and study whispering-gallery modes (WGMs) in SLMs with different lengths. The transmission spectra from 1530 nm to 1550 nm of several SLMs are presented and SLMs with different lengths are shown to have different transmission features. The maximal Q factor observed in the SLMs is 3.
