Methods for the fabrication of TS LED chips with improved light extraction and optics, particularly increased top surface emission, and the TS LEDs so fabricated are described. Non-absorbing DBRs within the chip permit the fabrication of the LEDs. The transparent DBRs redirect light away from absorbing...http://www.google.com/patents/US6015719?utm_source=gb-gplus-sharePatent US6015719 - Transparent substrate light emitting diodes with directed light output
