Abstract：

Although　the　resonant　cavity　light-emitting　diodes　(RCLEDs)　have　better　thermal　behavior　comparing　with　vertical-cavity　surface-emitting　lasers　(VCSELs),　the　emission　intensity　and　far-field　pattern　of　RCLEDs　still　depend　on　the　temperature.　A　conflict　exists　between　the　requirement　of　high　optical　intensity　and　increased　temperature.　The　multi-active　region　RCLEDs　with　two　MQWs　connected　by　a　tunnel　junction　can　solve　this　problem　through　the　over　100%　internal　quantum　efficiency.　In　this　paper,　simulations　of　the　optical　field　and　emitted　pattern　for　multi-active　region　RCLEDs　are　calculated　based　on　method　of　transfer　matrix　and　source　term,　and　comparison　with　single　active　region　RCLEDs　is　made　as　well　to　give　a　deep　insight　of　multi-active　region　RCLEDs.　©2009　IEEE.
