We present electroabsorption modulators integrated with distributed feedback lasers (EMLs) fabricated by a simple method. which combines the advantages of the selective area growth and double stack active layer techniques. The obtained EML device has a threshold current as low as 16 mA and optical power of larger than 10 mW at 85 mA laser current. Quite low chirp parameter of the fabr... https://bxxrnqd57cnjl.theisblog.com/35130280/wastewater-reuse
