Abstract
Dilated space switches on InP have a crosstalk level of about -28 dB, which is too low for application in large WDM networks. In this contribution the influence of stray light in the wafer on the crosstalk level of the dilated swicht is investigated. By placing titanium absorbers at both sides of the waveguiding structure of the switch, the stray light is removed from teh wafer, resulting in a crosstalk reduction of 3 dB in ths type of switch. In switches with lover crosstalk levels the reduction is even larger (6 dB)
