IdealPhotonics' 1100-1500nm DBR diode, based on an ultra-wideband tunable laser with InGaAsP/InP multiple quantum wells and segmented sampling gratings (±0.03nm accuracy), achieves an 80nm supercontinuous tuning range and wavelength stability of ±0.003nm/℃. In cross-band applications such as 1310nm fiber optic communication (50Gbps PAM4), 1380nm water molecule detection (0.1ppb sensitivity), and 1460nm medical lasers, it simultaneously achieves a 65dB side-mode rejection ratio and 0.002nm spectral resolution. Its innovative "silicon-based heterogeneous integration" technology reduces tuning power consumption by 60%, making it a revolutionary optoelectronic device covering the O/E/S/C/L bands.Employing InGaAsP/InP multiple quantum wells and sub-nanometer segmented sampling gratings (±0.02nm accuracy), this technology achieves 80nm ultra-wideband tuning and ±0.002nm/℃ quantum-level stability. It simultaneously achieves breakthroughs in three major fields: 1310nm high-speed communication (64Gbps PAM6), 1380nm trace gas detection (0.05ppb sensitivity), and 1460nm precision medicine. Its extreme performance of 68dB side-mode suppression ratio and 0.001nm spectral resolution, combined with innovative "silicon photonic heterogeneous integration + microfluidic tuning" technology, reduces power consumption by 70%, redefining the performance paradigm of ultra-wideband tunable lasers.
