    • Heat management systems for vertical cavity surface emitting laser (VCSEL) chips are provided. Embodiments of the invention provide substrates having, a vertical cavity surface emitting laser chip disposed on the substrate surface and electrically interconnected with the substrate, a thermal frame disposed on the substrate surface and proximate to at least three sides of the vertical cavity surface emitting laser chip, and a thermal interface material disposed between the at least three sides of the vertical cavity surface emitting laser chip and the thermal frame. The substrate can also include a transceiver chip that is operably coupled to a further integrated circuit chip and that is capable of driving the VCSEL chip.
    • 提供了垂直腔表面发射激光(VCSEL)芯片的热管理系统。 本发明的实施例提供了具有设置在衬底表面上并与衬底电互连的垂直腔表面发射激光器芯片的衬底,设置在衬底表面上并且靠近垂直腔表面发射激光器芯片的至少三个侧面的热框架 以及设置在垂直腔表面发射激光芯片和热框架的至少三个侧面之间的热界面材料。 衬底还可以包括可操作地耦合到另一集成电路芯片并且能够驱动VCSEL芯片的收发器芯片。
