Deeplight’s lasers achieve excepcionally narrow Hz-level linewidths based on a high-quality (Q) factor Whispering Gallery Mode (WGM) resonator. The combination of ultra-low linewidth and fast frequency modulation of our products, remains unparalleled and sits at the core of the conception of Deeplight itself.

Key features of Deeplight Narrow-linewith and frequency tunable lasers

  • Ultra-low intrinsic linewidth down to Hz-level.
  • Fast frequency modulation based on piezoelectric materials over 100 MHz-1 GHz range.
  • Packaged in a butterfly housing with output fiber.

There are two sub-families of Narrow-linewidth and frequency tunable lasers called NL-1550 and UNL-1550. Here are the typical specifications for both models Fill table:

Output power [mW] 1-10 1-10
Fiber Type PM PM
Intrinsic linewidth [Hz] < 20 (typ. 15) < 10 (typ. 1.5)
Integrated linewidth (100 ms) [Hz] < 5000 < 5000
PER [dB] > 25 > 25
Frequency modulation bandwidth [MHz] > 1 > 1

Further features are available on request, some additional features are:

  • Different operating wavelength
  • Different operating temperature
  • Included control electronics for current and temperature Optical isolator
  • Amplified output (maybe with SOA)

Examples of this and other features can be found in the customised solutions tab. Please feel free to contact us if your request is not reflected.
