Abstract:
A method of generating optical pulses using an active mode-locking laser that includes first modulation means, first routing means, optical selection means, second routing means, second modulation means and amplification means, said method comprising:modulating a lightwave via the first modulation means; routing the lightwave modulated by the first modulation means via the first routing means; selecting a modulation lightwave signal having a high frequency component by passing the lightwave routed by the first routing means through the optical selection means in a first direction; routing the lightwave selected by the optical selection means via the second routing means; amplifying the lightwave routed by the second routing means via the amplification means; modulating the lightwave amplified by the amplification means via the second modulation means; routing the lightwave modulated by the second modulation means via the second routing means; selecting a modulation lightwave signal having a high frequency component by passing the lightwave routed by the second routing means through the optical selection means in a second direction; routing the lightwave selected by the optical selection means via the first routing means; and supplying the lightwave routed by the first routing means to the first modulation means.
