Optical image of a hybrid integrated erbium-doped photonic integrated circuit-based laser, providing fiber-laser coherence and previously unachievable frequency tunability. Lasers have revolutionized ...
Using erbium-laser energy in wet canals in conjunction with EDTA (ethylenediaminetetraacetic acid) irrigation during root canal surgery yields cleaner root canal walls and more open tubules, according ...
As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, ...
