Optical preamplifier |
| 摘要 |
<p>The preamplifier has a first optical amplifier (10) which is connected to a photocell (40) via a wavelength converter (20) at a fixed wavelength (I0) and an optical filter (30) centered around the fixed wavelength. The wavelength converter can be a semiconductor optical amplifier with stabilized gain. The circuit can include a rejecting optical filter.</p> |
