    I am working with a Laser Diode and I need to observe the intensity of the diode in TE and TM polarizations. the Diode is polarized in the horizontal axis (linear polarization). Is it sufficient to use a half wave plate and rotate it by 90 degrees to observe TE and TM modes?

    Also, what kind of output should i expect while using a half wave plate in front of a linearly polarized source? Will I get maxima at pi/2 angles of the plate and minima at pi/4 angles?

    Thanks for the help!
