Full CMOS compatible III–V Microdisk tunable CW lasers for on chip optical interconnects

III-V Microdisk lasers have been fabricated on a 200 mm CMOS pilot line. In a first part lasers are coupled to Si waveguides and different coupling schemes are investigated. In a second section, lasers are coupled at two different points to modulate their emission, through an active control of the coupling losses. Two devices with different coupling schemes are experimentally studied, and their properties are compared.
