Abstract: Planar waveguide junctions are described with a waggled transition section connecting input waveguide sections with output waveguides sections, in which the waggled transitions have alternating segments matching the input waveguide and output waveguides to efficiently transition the optical signal. The planar waveguide junctions can be used to form efficient optical splitters, mixers, or taps.

Abstract: An ice fishing strike indicator preferably includes a support base and a strike indicator. The strike indicator preferably includes an indicator housing, a pop-up indicator and a trigger member. The pop-up indicator is slidably biased upward in the indicator housing. The trigger member preferably includes a support tube, a trigger rod and a fishing line reel. The support tube is retained by the indicator housing and adjustably retained by the support base. The trigger rod is slidably retained in the support tube. A trigger finger is formed on one end of the trigger rod and the fishing line reel is retained on the other end thereof. The trigger finger hooks into the pop-up indicator. Rotation of the fishing line reel by a fish strike causes the trigger finger to release the pop-up indicator. A light emitting strike indicator may be used for night time fishing.
