Abstract: A method includes forming an assembly of layers including an InP cap layer on an InGaAs absorption region layer, wherein the InGaAs layer is on an n-InP layer, and wherein an underlying substrate layer underlies the n-InP layer. The method includes removing a portion of the InP cap and n-InP layer by dry etching.

Abstract: Reward program management system for managing multiple rewards earned through participation in multiple reward earning programs of different earn partners by a person, the person having multiple identifiers, comprising: a server accessible to earn partners receiving reward information including rewards earned by the person and one of the multiple identifiers; a database storing the rewards earned by the person and the identifier associated with each reward; the server providing the person with an interface to receive information from the person regarding at least two of the multiple identifiers to create a set of linked identifiers; a computer processor retrieving and totaling the rewards earned by the person stored in the database in association with all of the identifiers of the set of linked identifiers to create a total reward; the server, accessible to burn partners, providing information regarding the total reward upon receipt from a burn partner of one of the set of linked identifiers.
