New avenues for light-matter interaction: Parity-time symmetry and non-ergodic behaviour of gain-loss transducer arrays


We investigate the use of gain and loss added to various structures in a Parity-Time (PT) symmetric fashion: firstly, in an otherwise canonical co-directional coupler, we attempt to optimize the total amount of loss needed for a switching operation by using a local modulation of gain. Secondly, we interrogate the possible statistical consequence of using… (More)
