Abstract: Embodiments reduce crosstalk between electrical interconnects by offsetting pairs of electrical interconnects in an electrical system to produce a staggered interconnect pattern for which magnetic flux through a loop formed by a victim interconnect pair is effectively canceled. Magnetic field vectors generated by an aggressor pair of interconnects can pass through a loop-bounded surface defined by a victim pair of interconnects in the system. In the staggered interconnect pattern, the victim interconnect pair is offset with respect to the aggressor interconnect pair so that the field vectors passing through the victim pair's loop-bounded surface in one direction are substantially balanced by the field vectors passing through the victim pair's loop-bounded surface in the opposite direction, thereby minimizing the effect of the aggressor pair's magnetic field on the victim pair. Since crosstalk is proportional to the rate of change of the magnetic flux, reducing the magnetic flux can reduce the crosstalk.

Abstract: For epitaxial-side-down bonding of quantum cascade lasers (QCLs), it is important to optimize the heat transfer between the QCL chip and the heat sink to which the chip is mounted. This is achieved by using a heatsink with high thermal conductivity and by minimizing the thermal resistance between the laser active region and said heatsink. In the epi-down configuration concerned, the active region of the QCL is located only a few micrometers away from the heatsink, which is preferable from a thermal standpoint. However, this design is challenging to implement and often results in a low fabrication yield if no special precautions are taken. Since the active region is very close to the heatsink, solder material may ooze out on the sides of the chip during the bonding process and may short-circuits the device, rendering it unusable. To avoid this happening, the invention proposes to provide a trench all around the chip with the exception of the two waveguide facets, i.e. the ends of the active region.
