Passive InP regenerator integrated on SOI for the support of broadband silicon modulators

Passive signal regeneration based on the Membrane InP Switch (MIPS) is demonstrated. Because of the high confinement of light in the active region of the MIPS, the device acts as a saturable absorber with a highly non-linear response. Using this effect, the extinction ratio (ER) of low-ER signals can be tripled and a receiver sensitivity enhancement of 4.5dB is demonstrated using an input signal at 1Gb/s with an ER of 2dB. Regenerator operation up to 5Gb/s is demonstrated and using a device simulator a strategy to reach higher bitrate operation is propose

All-optical membrane InP switch on silicon for access applications

Using an integrated membrane switch on SOI, optical clock distribution is achieved while all-optical switching of datapackets is maintained. Transmission through 25km SMF is demonstrated with 1.5dB penalty, limited by signal OSNR and pump extinction

Membrane InP saturable absorbers on silicon as building blocks for transparent optical networks

As silicon photonics continues to gain research and industrial relevance, some of the building blocks in this technology such as modulators and switches still suffer from limitation when it comes to insertion losses and/or extinction ratio. In the past two years we have been investigating a promising new building block for silicon on insulator (SOI) circuits which is based on ultra-thin narrow stripes of InP bonded on top of SOI, which operate as saturable absorbers at very low optical power levels. The unique properties of these membrane InP switches (MIPS) make them ideally suitable as complementary components to SOI devices. By controlling the band gap of the active layers in the membrane as well as the confinement of light critical properties of such MIPS can be determined and tailored to specific applications. In this talk we will highlight two exciting applications of MIPS on SOI. First we will show how they enhance the performance of silicon based modulators by regenerating the signal through their non-linear response. Secondly we will show how they may solve a unique engineering challenge for next generation access networks by operating as optically controlled switches with high extinction ratio and no electrical power supply

Las competencias matemáticas a partir de una estrategia didáctica en un ambiente de geometría dinámica

Se presenta una experiencia desarrollada en el contexto de la asignatura Práctica Educativa II del profesorado en matemática de la Facultad de Ciencias Exactas y Naturales de la Universidad Nacional del La Pampa. Dicha asignatura tiene entre sus objetivos la adquisición de competencias para diseñar unidades didácticas sobre los distintos contenidos curriculares de Matemática. La experiencia está centrada en la resolución de problemas con uso de tecnología, vivenciada por los futuros profesores para su posterior planificación y transferencia al ciclo básico de la educación secundaria. En particular se trabajó en el diseño de una actividad para la enseñanza de conceptos geométricos usando tecnología, con una mirada reflexiva al modo de plantear relaciones entre álgebra y geometría
