Phase Contrast and Differential Interference Contrast Microscopy

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Area of Science:

Photonics and Optical Engineering
Quantum Metrology
Integrated Optics

Background:

Optical frequency combs are essential for precision measurements.
Microcombs offer chip-level integration but face limitations in stabilizing broadband spectra.
Current microcombs lack simultaneous electronic stabilization and broad bandwidth.

Purpose of the Study:

To overcome the limitations of current microcomb technologies.
To achieve simultaneous electronic stabilization and broadband spectra in microcombs.
To enable chip-scale optical frequency combs for practical applications.

Main Methods:

Interleaving an electro-optic comb with a parametric microcomb spectrum.
Utilizing a novel approach for direct control and stabilization of microcomb spectra.
Achieving large mode spacing (>140 GHz) without external mode-locked lasers.

Main Results:

Demonstrated direct control and stabilization of a microcomb spectrum with large mode spacing.
Attained a residual 1-sec instability of 10⁻¹⁵ for microcomb spacing.
Achieved microwave reference limited absolute instability of 10⁻¹² at 140 GHz mode spacing.

Conclusions:

Successfully combined electronically detectable mode spacing with broadband spectra in microcombs.
Paved the way for chip-level, out-of-the-lab optical frequency comb devices.
This advancement is critical for widespread microcomb applications in metrology and spectroscopy.
