Se ha diseñado, fabricado y caracterizado un divisor de haz micro-optico con dos geometrias diferentes, 1x2 y 1x4. La fabricacion se basa en el metodo de litografia blanda y requiere un unico paso fotolitografico para la definicion del master. El dispositivo se replica usando poli(dimetilsiloxano) (PDMS). El funcionamiento del dispositivo se basa en la implementacion de lentes, espejos y divisores de haz, definidos unicamente con PDMS y aire. Tambien se han fabricado unos sistemas de auto-alineamiento para poner las fibras. Las perdidas en cada division del haz son de 7.8 ¿} 1.2 dB.

A micro-optical beam splitter for integrated optical devices has been designed, fabricated and characterized. Two main configurations of the beam splitters are defined: 1x2 and 1x4. The fabrication is based on soft-lithography and requires a single photolithographic step for master definition. The device is replicated in poly(dimethyl-siloxane) (PDMS). Its working principle is based on total internal reflection. Optical elements e.g., lenses, mirrors and beam splitters, based on PDMS and air as constituent materials are defined. A self alignment system for optical fibers has been also fabricated. Losses of 7.8 ¿} 1.2 dB for a single beam division are obtained.
