研究目的
To demonstrate a high-power blue emitting superluminescent diode (SLD) with a tilted-facet configuration, achieving a record high power-bandwidth product.
研究成果
A record high-power blue emitting SLD of 457 mW at an injection current of 1 A was demonstrated by utilizing a 12° tilted-facet design, resulting in a record high power-bandwidth product of above 2970 mW·nm with wall-plug and slope efficiencies of 7.9% and 0.9 W/A, respectively.
研究不足
The study does not discuss the long-term reliability or the scalability of the SLD for industrial applications.
1:Experimental Design and Method Selection:
The SLD utilizes a 12° tilted-facet waveguide to suppress feedback of light in the resonating cavity under high current injection.
2:Sample Selection and Data Sources:
A 15-μm-wide ridge waveguide SLD was etched to ~1000 μm in length and the facet was polished by focused ion beam (FIB) milling processing.
3:List of Experimental Equipment and Materials:
The SLD was tested in a customized tester with a Keithley 2520 diode laser testing system and a thermoelectric cooler (TEC) to stabilize the operating temperature at 22 °C.
4:Experimental Procedures and Operational Workflow:
Light-current -voltage (L-I-V) characteristics were measured under a pulsed operation (duty cycle of 2%,
5:8 kHz). Data Analysis Methods:
The electroluminescence (EL) spectra were measured using an Ocean-Optics HR4000 spectrometer at different currents ranging from 100 mA to 1 A.
