There is currently a great deal of interest in flat dielectric micro-cavities due to their numerous practical applications and their ability to address fundamental physics issues. But apart from circular cavity, exact expressions of wave-functions and spectrum are still unknown for all other cavity shapes. The difficulty originates from two separated factors: non-linearities induced by the boundary...
Summary form only given. Little attention has been paid to nonlinear optical microcavities whereby a prerequisite for quadratic effects is an in-plane transverse non-centrosymmetric orientation of the active part. We therefore propose optical poling as a more suitable means to induce such a configuration to a dye-grafted polymer medium than the traditional electric field thermal poling. In the all-optical...
