Stretchable optical diffraction grating from poly(acrylic acid)/polyethylene oxide stereocomplex
Jinghan He, Andre Kovach, Yunxiang Wang +3
Optical gratings are a key component in many spectroscopy, communications, and imaging systems. While initially static elements, advances in optical materials have enabled dynamica…
Cascaded Stokes and anti-Stokes laser based on an optical resonator with a self-assembled organic monolayer
Andre Kovach, Arynn Gallegos, Jinghan He +2
Due to their high circulating intensities, ultra-high quality factor dielectric whispering-gallery mode resonators have enabled the development of low threshold Raman microlasers.…
Nonlinear nanophotonic devices in the Ultraviolet to Visible wavelength range
Jinghan He, Hong Chen, Jin Hu +7
Although the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. Howe…
Optically tunable microresonator using an azobenzene monolayer
Andre Kovach, Jinghan He, Patrick J. G. Saris +2
Photoswitchable organic molecules can undergo reversible structural changes with an external light stimulus. These optically controlled molecules have been used in the development…
All-optical reversible controls of integrated photonics by self-assembled azobenzene
Jinghan He, Andre Kovach, Dongyu Chen +3
The next frontier in photonics will rely on the synergistic combination of disparate material systems. One unique organic molecule is azobenzene. This molecule can reversibly chang…
Emerging material systems for integrated optical Kerr frequency combs
Andre Kovach, Dongyu Chen, Jinghan He +5
The experimental realization of a Kerr frequency comb represented the convergence of research in materials, physics, and engineering, and this symbiotic relationship continues to u…
