| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | By the two-dimensional triangular holey structure, a record high-power stable single-mode operation was demonstrated in oxide confined 850-nm vertical-cavity surface-emitting lasers. For two types of hole arrangements, single-mode lasing operation was observed with different near field patterns, i.e., a single spot pattern and a floral pattern. The former showed an output power of 2 mW with a high side-mode suppression ratio (SMSR) of 45 – 50 dB, which is explained by the selective loss mechanism. The latter showed a high power of 7 mW with an SMSR of 40 dB. The observed lasing spectrum and peak centered far field pattern indicate that it is a deformed fundamental mode whose bright spots extending over the device are coherently oscillating with the same phase. This device structure will be effective for the enhancement of single-mode power in devices with any material system. | |
