85°C Operation of Single-Mode 850 nm VCSELs for High Speed Error-Free Transmission up to 1 km in OM4 Fiber

Single-mode 850 nm oxide-confined VCSELs with integrated mode-selective filter are developed. The fabricated devices have demonstrated 32 Gb/s (room temperature) & 26 Gb/s (85°C) error-free transmission over 500 m OM4 fiber, and 28 Gb/s (room temperature) & 22 Gb/s (85°C) over 1 km OM4 fiber.
