Abstract
Microelectronic grade semiconductors display excellent figure of merits for second-order optical nonlinearity effects. However, most of them are not birefringent and cannot be properly phase-matched for efficient optical frequency conversion. This paper describes the different phase-matching scenarios which are currently developed in different laboratories to solve this problem. If successful, this field of research will open the way to future complete integrated optical parametric oscillators.
