Speed Enhancement of a Single-Mode FP-LD-Based Switch Using the Weak-Lock Technique

IEEE Photonics Journal, 2014
A technique called weak-lock (WL) has been proposed and applied to a simple optical on/off switch to increase its working speed from 1 to 12 Gb/s with clear output waveforms, whereas the required injection power is decreased.

On phase noise of self-injection locked semiconductor lasers [PDF]

SPIE Proceedings, 2014
We discuss our recent progress in iimproving the phase noise of a semiconductor laser using self-injection locking of to a mode of a high-Q whispering gallery mode resonator. Locking efficiency is analyzed for semiconductor distributed feedback (DFB) as well as Fabry-Perot (FP) lasers operating at 690nm, 1060nm, 1550nm, and 2000nm.

Disruption of the SNRPF–DDX24–E2F4 Feedback Loop Uncouples Splicing and Transcriptional Regulation to Suppress Ovarian Cancer Progression

Advanced Science, EarlyView.
This study identifies SNRPF as a critical oncogenic driver in ovarian cancer. By regulating a self‐sustaining SNRPF–DDX24–E2F4 feedback loop through intron retention and nonsense‐mediated decay, SNRPF couples RNA splicing with transcriptional regulation to promote tumor progression.
