Vector Photonics has successfully produced 1300nm, all-semiconductor PCSELs (Photonic Crystal Surface Emitting Lasers) targeting 800Gb, datacoms applications. The PCSEL arrays emit four, concurrent, 1300nm wavelengths, with a SMSR (Side-Mode-Suppression Ratio) measurement of around 35dB. This revolutionary development in laser capability comes as the datacoms industry meets at the OFC exhibition in San Diego, later this month.
