研究目的
To demonstrate a monolithically integrated Vernier laser on an InP nanophotonic membrane platform for wide tuning range applications.
研究成果
The monolithically integrated Vernier laser on an InP nanophotonic membrane platform demonstrates a wide tuning range of 21 nm, high SMSR (>35 dB), and sufficient output power (>1.3 mW), making it suitable for integrated WDM systems and other applications.
研究不足
The tuning range achieved was 21 nm, covering 6 channels instead of the designed 8, possibly due to fabrication-induced changes in waveguide dimensions affecting the free spectral range (FSR) of the rings.
1：Experimental Design and Method Selection
The study involves the design and fabrication of a Vernier laser with two-ring filters in the cavity on an InP membrane platform. The methodology includes thermal tuning of the rings to achieve a wide tuning range.
2：Sample Selection and Data Sources
The samples are fabricated using a double-side membrane processing approach, involving 12 lithography steps. Data is collected from the characterization of the laser in continuous wave regime.
3：List of Experimental Equipment and Materials
InP membrane platform, semiconductor optical amplifiers (SOA), tunable ring resonators, photonic crystal reflectors, micro-ring filters.
4：Experimental Procedures and Operational Workflow
The fabrication includes dry etching, metal deposition, wet etching, and wafer bonding. Characterization involves measuring VI and LI curves, optical spectra, and wavelength shift depending on heater power.
5：Data Analysis Methods
Analysis includes measuring threshold current, side mode suppression ratio (SMSR), output power, and tuning range. Statistical techniques are used to analyze the performance metrics.
