We show that temporal pulse compression can be achieved by using an integrated, low dispersion, high index glass (Hydexreg) waveguide. Sub-ps compression is demonstrated for peak powers lower than 100 W using a 45 cm spiral waveguide.

Characterization of intense light pulses approaching the single-cycle regime is currently hindered by the limited resolution of available metrological techniques. However if attosecond sampling of the electric field (1) of such pulses is employed, access into the fine features of their waveform opens up new possibilities for precise temporal shaping and control. We demonstrate that due to this capability, we can tune ultrashort pulses with sub-cycle resolution and can temporally compress them down to 1.2 light field oscillations. Such pulses carry more 70% of their several hundreds of microjoule energy within only one field oscillation. We will discuss the impact of these tools in steering and controlling of electrons at light frequencies, giving rise to lightwave electronics (2), as well as, their novel applications for the generation of ultrashort intense bursts of light in the deep and the vacuum ultraviolet (3).

There are many applications that require mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) dual-band focal plane arrays (FPAs). For example, a dual-band FPA camera would provide the accurate temperature of a target with unknown emissivity which is extremely important to the process of identifying objects based on their surface temperature. Dual-band infrared FPAs can also play many important roles in Earth and planetary remote sensing, astronomy, etc.

We demonstrate mode-locked operation of an all-normal dispersion Yb-fiber oscillator without the use of bulk bandpass filter. A section of PM-fiber incorporated into the cavity acts as a filter, paving the way towards an all-fiber oscillator based on off-the-shelf components.
