Notes: The recently proposed concept of periodic gain, i.e., dividing the active region into segments placed at optical electric-field standing wave maxima, has been shown to greatly reduce the threshold gain requirement of the active media by up to a factor of 2 in high-finesse vertical cavity surface-emitting lasers. The lasing wavelength is determined by the period of the standing wave; however, previous analyses of these structures have failed to show that a similar enhancement effect occurs for the index shift resulting from the active segments as well. In this communication, we show that effects on both gain and index can be rigorously derived from conventional transmission scattering theory.
