Band flipping and bandgap closing in a photonic crystal ring and its applications
Xiyuan Lu, Ashish Chanana, Yi Sun +3
The size of the bandgap in a photonic crystal ring is typically intuitively considered to monotonically grow as the modulation amplitude of the grating increases, causing increasin…

Multi-mode microcavity frequency engineering through a shifted grating in a photonic crystal ring
Xiyuan Lu, Yi Sun, Ashish Chanana +3
Frequency engineering of whispering-gallery resonances is essential in microcavity nonlinear optics. The key is to control the frequencies of the cavity modes involved in the under…

Kerr optical parametric oscillation in a photonic crystal microring for accessing the infrared
Xiyuan Lu, Ashish Chanana, Feng Zhou +2
Continuous wave optical parametric oscillation (OPO) provides a flexible approach for accessing mid-infrared wavelengths between 2 m to 5 m, but has not yet been integrated i…
