| 英文摘要 | we demonstrated oxide-confined 850-nm vertical-cavity surface-emitting lasers (vcsels) with a two-dimensional petal-shaped holey structure composed of several annular-sector-shaped holes. four types of devices with different hole numbers were designed and fabricated. the measured results showed that the larger hole number was beneficial to purifying the lasing mode, and realizing the single-mode operation. the side mode suppression ratio (smsr) exceeded 30 db throughout the entire drive current. mode selective loss mechanism was used to explain the single-mode characteristic. the single-mode devices possessed good beam profiles, and the lowest divergence angle was as narrow as 3.2 degrees (full width at half maximum), attributed to the graded index profile and the shallow etching in the top distributed bragg reflector (dbr).; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-22t14:07:42z no. of bitstreams: 1 single-mode holey vertical-cavity surface-emitting laser with ultra-narrow beam divergence .pdf: 438221 bytes, checksum: ec19825bf352fd61f5bf75ab56cae87d (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-22t14:13:36z (gmt) no. of bitstreams: 1 single-mode holey vertical-cavity surface-emitting laser with ultra-narrow beam divergence .pdf: 438221 bytes, checksum: ec19825bf352fd61f5bf75ab56cae87d (md5); made available in dspace on 2010-04-22t14:13:36z (gmt). no. of bitstreams: 1 single-mode holey vertical-cavity surface-emitting laser with ultra-narrow beam divergence .pdf: 438221 bytes, checksum: ec19825bf352fd61f5bf75ab56cae87d (md5) previous issue date: 2010; chinese national key basic research special fund/cnkbrsf 2006cb921705; national natural science foundation of china 10634080 60677046 60838003 ;national high technology research and development program of china 2007aa03z410 2007aa03z408; 其它 |
