DOI: 10.1063/1.4997026
Abstract: We observe lasing emission from an organic microcavity structure at room temperature with a sunflower-like pattern closely resembling Laguerre-Gauss modes. Simultaneously, measured angle-resolved emission spectra below and above the lasing threshold demonstrate the coexistence of… read more here.

DOI: 10.1103/physrevb.101.125432
Abstract: The dynamical encirclement around a second order exceptional point (EP) and corresponding chirality driven nonadiabatic modal dynamics have attracted enormous attention in the topological study of various non-Hermitian systems. However, dynamical encirclement around multiple second-order… read more here.

DOI: 10.1109/tcsii.2022.3169224
Abstract: Fractional- $N$ frequency synthesizers are characterized by unwanted periodic components in their frequency spectra called spurs. In communications applications, spurs reduce the signal to noise ratio of the system; in clocking they add jitter; in… read more here.

DOI: 10.1109/tmtt.2021.3079250
Abstract: Nonreciprocal electromagnetic devices allow signals to propagate asymmetrically along opposite directions, enabling essential functionalities for several microwave and optical technologies. Branching out from the conventional approach involving a dc magnetic bias, different avenues have been… read more here.

DOI: 10.1364/oe.404177
Abstract: We have investigated the effect of cascaded optical nonlinearity on the spatial beam properties of a femtosecond optical parametric oscillator (OPO). The OPO was operated with a tunable phase mismatch by varying the angle of… read more here.
