May 24, 2013 Time Contribution Francois Work - R&D optics 0.50 HR 2013 May 21 (5.5 h + 1.5 h): prepare 5 joint-type transducers in angle using Ivan's pre-bent glass capillaries. Result: broke one, fried one, one has a damaged mirror. 2 left to connectorize. Connectorization failed. 0 transducer made.... 2013 May 22 (4h): goal: mirror 4 levers, connectorize one transducer. silvering quality tests: played with number of silver layers and reaction time: red lever: 3 times one minutes shaking. Intensity = ? one black strip lever: one time one minute shaking. Intensity = ? two black strips lever: one time 2 minutes. Intensity = ? Arranged power supply memories for shrinking: M1 = 0 M2 = 0.32 A x 0.67 V = 0.2 W M3 = 0.4 x 1 = 0.4 W M4 = 0.6 x 0.1 = 0.6 W Determined ideal length for delivery fiber at the very beginning (before cleaving 1 cm both side) = 16.7 cm Result: made one pre-bent joint-type transducer. 2013 May 24 (0.5 h): tested transducer with LED Mosquito: it works Make Photonics - Joint-type transducer Prototype Material - Joint-type transducer: Joint-type transducer glass fiber

May 21, 2013 Time Contribution Francois Work - R&D optics 7.00 HR prepare 5 joint-type transducers in angle using Ivan's pre-bent glass capillaries. Result: broke one, fried one, one has a damaged mirror. 2 left to connectorize. Connectorization failed. 0 transducer made.... Make Photonics - Joint-type transducer Prototype Material - Joint-type transducer: Joint-type transducer glass fiber
May 20, 2013 Time Contribution Francois Work - R&D mechanics 3.68 HR try bonding performance of "seal'n peel" sealant to bind 2 optic fibers. Mirrored and controled 4 levers. Make Optical - Joint-type transducer
May 16, 2013 Time Contribution Francois Design and prototyping - do not use 1.50 HR Open prepared a OMEM concept for the joint-type and coordinated with Dr Peter (Poly)
May 15, 2013 Time Contribution Francois Work - Office 1.00 HR browsed internet for canadian O-MEMS labs.
May 14, 2013 Time Contribution Francois Work - Information mining 4.00 HR found and read papers on O-MEMS. Contacted a researcher on O-MEMS.
May 13, 2013 Time Contribution Francois Work - R&D optics 7.00 HR Open did 3 joint-type transducers with special shape lenses.
May 1, 2013 Time Contribution Francois Work - R&D chemistry 1.92 HR first I will verify fibres with lenses: they are not good except one, so I make some. then mirror some levers, and shrink lens fibers with levers. for levers: fiber are cut 8 cm long.
April 15, 2013 Time Contribution Francois Work - Accounting and Finance 0.50 HR paid taxes on salary
March 16, 2013 Time Contribution Tibi Work - R&D optics 1.00 HR I am working with Francois on the new Joint-type transducer, making prototypes for the following design: Convex type https://docs.google.com/drawings/d/1KyzF-MpkvOXdisDqgH_yGBO9UF6DN-m7aoV9a-eRmFg/edit The goal is to make a few transducers that will be used at Phil's lab for the Mosquito Scientific Instrument System. The other day I observed how the curvature of the tip of the delivery fiber was affecting the exit angle of the light. It turns out that the angle starts to diminish when the fiber tip it melted a lot to make a large ball. The ball for smaller exit cone is larger than the diameter of the shrinking tube. The conclusion was that we need to have a small curvature, to avoid fabry perot, but the sensitivity will not improve a lot, because we cannot reduce the exit cone of the light. These tests were done with visible green light. Today we'll connectorize the convex delivery fiber to a mirrored lever that was made the other day by Francois, and explore the performance of this transducer. We are now testing different convex delivery joint-type for intensity variation with gap size. We see some strange behavior, an increase in intensity within 50 microns, with a pick in the middle, and after the intensity diminishes normally for the geometrical mode. Make Joint-type transducer

March 13, 2013 Time Contribution Tibi Work - R&D optics 3.00 HR Open worked on the joint-type transducer with round delivery fiber tip. The idea here was to compare different curvatures of the ball tip in terms of the exit angle of the cone of the light. It turns out that a very large ball works better, which does not fit into the normal shrinking tube er use.
