The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high speed control of optical field coherence.

This figure presents the results of distributed strain sensing over an approximately 100-m-long optical fiber utilizing BOCDR with periodic pseudo-random modulation. The top diagram illustrates the ...

Gaps in the coherence spectrum of diode lasers have been known to hinder research. Anselm Deninger and Thomas Renner look at how these gaps are being filled and the applications that are benefiting ...

Researchers at the Paul-Drude-Institute for Solid State Electronics (PDI) have discovered a novel modulation regime in semiconductor-based lasers, characterized by "acceleration beats." This regime ...
