Patent number: 10996493Abstract: An optoelectronic component includes an optical waveguide including at least one passive and at least one active section. The active section has at least one layer formed from a two-dimensional material. The layer composed of the two-dimensional material is arranged at least partly in a waveguide core of the active section or in a manner at least partly adjoining the waveguide core of the active section. The difference in refractive index relative to the same wavelength between a core material forming the waveguide core of the active section and a cladding material forming a waveguide cladding of the active section is greater than the difference in refractive index between a core material forming a waveguide core of the passive section and a cladding material forming a waveguide cladding of the passive section.Type: GrantFiled: November 24, 2017Date of Patent: May 4, 2021Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventor: Moritz Kleinert

Patent number: 9780525Abstract: An optoelectronic oscillator for generating an optical and/or electric pulse comb, comprising a monolithically integrated passively mode-coupled semiconductor laser and an optical feedback loop which guides a part of the optical radiation of the semiconductor laser and feeds said part back into the semiconductor laser as feedback pulses. Without the influence of the feedback pulses, the semiconductor laser would emit comb-like optical pulses, hereafter referred to as primary pulses, and in the event of an influence, emits comb-like output pulses which have been influenced by the feedback pulses, said output pulses having a lower temporal jitter or less phase noise than the primary pulses. The feedback loop is damped between 27.5 and 37.5 dB, and the time lag of the feedback loop is selected such that each feedback pulse is incident within the temporal half-value width of each subsequent primary pulse.Type: GrantFiled: June 12, 2014Date of Patent: October 3, 2017Assignee: Technische Universität BerlinInventors: Dejan Arsenijevic, Moritz Kleinert, Dieter Bimberg, I
