The ultra-narrow linewidth tunable C++ Laser Micro-ITLA hybrid photonic integrated circuit module from NeoPhotonics boasts a tuning range of 6 THz, covering the full “Super C-band,” which is 50 percent more spectrum than a standard 80 channel, 50 GHz spaced laser.

The C++ Laser supports full gridless tuning and accommodates any channel spacing, including 50, 75, 100, 125, and 150GHz. This new laser is based on the same high performance external cavity architecture as NeoPhotonics’ Micro-ITLA product line. The C++ Laser maintains comparable ultra-narrow linewidth, low phase noise and low power consumption, for which the current product is known, over a full 6 THz tuning range. The C++ Laser can tune over 80 channels with a 75 GHz per channel spacing, for example, to fully capture the increase in fibre capacity generated by these newer modulation approaches. Similarly the C++ Laser can tune over 120 channels on a standard 50 GHz grid spacing.
