The speed of light in a perfect vacuum – a well-known fact, a fundamental constant, a universal truth. This law has been a major principle of modern physics and in no small part does it define our understanding of the … Read More
Besides visible light optics, many strides are being done to improve our capability to harness information using other wavelengths of light. One such wavelength range is in the sub-millimeter range, or in terms of frequency, the terahertz (THz) domain. Recently, … Read More
In this letter published in Optics Letters on May 3, 2016, the group proposes a phase retrieval technique where the set-up uses a spatial light modulator (SLM) as a diffuser to enhance the variation in the intensity of light. Using … Read More
Photonics technology benefits when a beam of light can be manipulated without distorting its phase and intensity profile. This means that even after manipulation the information embedded in the beam do not get loss or jumbled. Recently, an orbital angular … Read More

Members of the Photonics Research Laboratory joined the 33rd Physics Congress of the SPP (Physics Society of the Philippines) held last 3-6 June, 2015 at the University of Northern Philippines, Vigan, Ilocos Sur, Philippines. The Photonics Research … Read More
The group developed a method to generate two-dimensional temporal coherence maps for ultrafast lasers using statistical fringe analysis of reconstructed phase maps.
By changing the phase temporally, the direction of motion of a rotating particle can be detected.
