We demonstrate compact, monolithically integrated thulium-doped tellurium oxide microring
lasers on a low-loss silicon nitride platform. We observe lasing in the wavelength range of …

In the realm of thin film fabrication, Atomic Layer Deposition (ALD) is a versatile technique
that facilitates the growth of high-quality and precision films for various applications, such as …

We present a multiple microrings channel integrated chip and develop a signal processing
method that enables parallel sensing with this chip. We utilize fast Fourier transform (FFT) …

A numerical analysis of a compact microring resonator that was defined on a yttrium-
aluminum-garnet (YAG) thin film bonded on top of a SiO2 cladding layer and operated at the …

Here we present a new measurement method for the characterization of photonic integrated
circuits (PIC) with an ultrahigh resolution, speed, and sensitivity that outperforms the existing …

Optical cavities are important parts of many scientific and industrial instruments and have
been widely studied in the field of optics and photonics. The Surface nanoscale axial …
