(color online) Spectrums of 10A under 1.5 V (a) and 2 V (b) reverse bias, and the spectrum of 10B under 0.9 V (c) reverse bias. The black arrows show the wavelength changes direction when injection current increases. (d) Emission wavelengths of 10A and 10B with the increasing injection current under 0 V, 0.9 V, 1.5 V, 2 V reverse biases and 0 V, 0.9 V reverse biases, respectively. (e) Calculated ratio for 10A. The red thick line indicates blue shift. (f) Calculated ratio for 10B. The red thick line indicates blue shift.
