1. EL and PL of uncoated sample with arm-arm injection scheme By Shu-man Liu 2006-3-9

2. Sample: 8_4_05.2#2E 1.Sample structure and composition 2.MicroPL scanning along to the wire 3.MicroPL with forward bias below the EL threshold 4.EL measured at 大部屋の奥 5.EL measured at 大部屋の右 6.Lasing under optical pumping with and without forward bias 7.PLE

3. Structure

4. MicroPL scan along the wire Standby

5. PL under various bias PL decreases suddenly and then increases with bias voltage.

6. EL measured at 大部屋の奥 On-axis Emissive position changed

7. EL measured at 大部屋の右 (2K-80K)

8. Lasing by optical pumping with and without forward bias Standby Bias=1.5V

9. Supplementary Experiments in the near future EL and PL images Polarization dependent PLE Absorption by Hakki-Paoli method
