Figure 4From: Top-Hat HELLISH-VCSOA for optical amplification and wavelength conversion for 0.85 to 1.3μm operationMeasured I - V and integrated EL intensity versus applied voltages for both polarities at room temperature. (a) Current–voltage and (b) integrated EL intensity characteristics for 1- and 1.6-mm-long THH-VCSOA using p- and n-channel configuration (12 ± V34G) under forward and reverse bias at T = 14°C.Back to article page
