In a device for mixing a first input optical signal (Ps) and a second input optical signal (Pl), a polarization beam splitter (10) receives the first and second input optical signals (Ps,Pl). Each of the first and second input optical signals (Ps,Pl) is separated into polarized optical signals having different polarization planes. Each polarized optical signal is divided into divided optical signals which are transmitted along acutely intersecting paths in a mixer (15,16) which mixes the divided optical signals corresponding to the first and second input optical signals (Ps,Pl). The mixed optical signals are then focused. |
