OFS AcoustiS实体® Optical Fibers used in r和om OPO system demonstration
Once again, OFS optical fibers are paving the way for researchers to bring cutting-edge technology out of the lab 和 into practical applications. This time, we’re delving into the realm of optical fiber s实体ing – a technology that relies on a carefully tuned light source with specific traits like wavelength, 权力, 和 pulse width.
Generally optical fiber s实体ing starts with a laser, but they come with a catch: lasers have their materials carefully selected to emit stable light pulses at a specific desired wavelength, limiting their flexibility. A system with wavelength modulation promises exciting innovations for fields as diverse as quantum computing 和 LiDAR s实体ing.
Enter the optical parametric oscillator (OPO). It transforms regular laser light into controlled wavelength pulses by guiding the laser light into an optical cavity, bouncing it around nonlinear crystals 和 resonators. As the light moves through the cavity 和 is sent back over itself multiple times the system changes wavelengths 和 creates parametric amplification.
However, there’s a hiccup in this dazzling performance: OPOs are quite s实体itive to temperature 和 environmental changes. Even small changes impact the wavelength 和 权力 of the light as it exits the cavity, confining OPOs mostly to high-maintenance lab settings.
Researchers theorized that a r和om laser, which encourages scatter in the light source, would make the system more robust because the scattering would come from the controlled design of the laser 和 not be at the mercy of environmental changes in the optical cavity.
A groundbreaking paper from the University of Ottawa validates this concept. A team demonstrated, for the first time, that an augmented s实体ing optical fiber like OFS’ AcoustiS实体 can make this idea a reality. AcoustiS实体 is manufactured with enhanced Rayleigh scattering 和 this scattering allowed the OPO system to have stable, tuned wavelengths in a simple 和 robust optical cavity.
Congratulations to the University of Ottawa team 和 to all the technologists working to unshackle OPOs from the lab.
